Microsoft Office 2013 Review!



3 stars out 
Microsoft Office 2013 is a significant update to the world's leading office suite. It may be lacking a killer new feature, but the myriad improvements woven throughout the key applications are a triumph. It's fast, responsive, and with a few months of refinement yet to come, looks set to be the best Office yet.
This is a preview of the Microsoft Office 2013 that gives our first impressions based on the specification and/or limited hands-on experience. We'll update it to a full review with a CNET UK rating once our testing is complete. Click the 'Alert Me' button to get an email when this preview is updated.

Good

  • Revamped interface
  • Faster and more responsive
  • Online integration

Bad

  • Its most important innovation, touch, will only be of interest to tablet users
Microsoft Office remains hugely popular (well, as popular as a spreadsheet and document creator can be), but with a raft of free office suites to compete with, it's got its work cut out to stay on top of the pile. So what thrilling bells and whistles will the latest 2013 edition offer to save you from a soporific slump at your desk?
Office for Mac was last updated in October 2010, so this time around it's Windows users who get a tasty new set of tools, with revamped versions of Word, Excel, PowerPoint, Publisher, OneNote and Outlook.
You can download the customer preview right now by following this link, and install it on up to five PCs. In the meantime, I'll run through the new features in the suite's four headline applications: Word, Excel, PowerPoint and Outlook.

Look and feel

This is the fifteenth PC edition of Office. When it ships it'll be available for the 32 and 64-bit versions of Windows 7 and 8 and -- importantly -- the version built to run on ARM processors. The latter will open it up to tablet devices and, if the rumoured iOS edition doesn't ship in the interim, could be enough to give Microsoft's nascent Surface tablets a significant boost.
It's not surprising that the interface has had a significant overhaul. In places, it now sports the Metro interface, which first appeared in later releases of Encarta and now fronts Windows Phone and half ofWindows 8.
This is most obvious when you click the file menu, which is highlighted with the application's colour. So it's blue in Word, green in Excel, orange in PowerPoint and so on. Rather than dropping down a menu or changing a ribbon along the top, this actually switches you to a Metro-style interface for performing common tasks such as opening and closing, protecting your file and checking for compatibility.
The disconnect between this and the editing environment isn't quite as stark as between the Metro and traditional 'desktop' halves of Windows 8, but it's still a slightly uncomfortable jump.

Some parts of the Office 2013 applications sport the Metro design used in Windows 8 and Windows Phone (click image to enlarge).
Overall, the button graphics have been simplified and the colours have been knocked back, so there's less visual clutter and fewer distractions from the actual working area.
Every application in the suite is touch enabled, and Microsoft has even built in a specific touch mode that gives the various interface elements a little extra space so they're easier to tap.

Activate the Touch mode and the interface elements in each application are given a little extra space to make them easier to tap.

Online integration

Office 2013 integrates with Microsoft SkyDrive to make your documents available not only on your primary work machine, but also any others logged in to the same account, including mobile devices.
Microsoft Office 2013 screen grab
SkyDrive integration makes it easy to work with a common set of documents across each of your devices.
You'll need a Windows Live ID to log in -- as you will to download the Office Customer Preview -- after which it'll appear in the Windows Explorer sidebar so it's always available through the regular File dialogs and the Metro-style File screens.
Documents saved to SkyDrive can be shared with people you're collaborating with. You can also give presentations remotely using the Office Presentations Service, even if your audience members don't have their own copy of PowerPoint.
Each of the constituent applications features a template chooser that gives you access to a generous library of templates stored on Microsoft's servers. They are downloaded to your PC when you want to use them and provide the basis for a new document. Be prepared to do some tweaking here and there as some have a US bias, with dollars on financial spreadsheets and an American slant to the 'resumes'.

The extensive template library downloads documents from Microsoft's servers, whenever you want to use them (click image to enlarge).

Integrating with blogs and services

Microsoft's wrists are clearly still smarting from the slap it got for favouring Internet Explorer over its rivals. That's good news for us users, as Office 2013 is more aware of third-party services than any other suite.
You can publish directly to common blogging platforms, including WordPress, Blogger and TypePad, and add new services to your integrated Office account. Doing so will let you add photos and videos from Flickr and YouTube, and share documents with colleagues on business networking site LinkedIn.
Microsoft Office 2013 screen grab
The sharing tools and integration of third-party services in Office 2013 can't be beaten right now (click image to enlarge).
It's also taken a step away from promoting its own file formats over all others. Word's .doc and .docx, and Excel's .xls and .xlsx have established themselves as the primary formats used in businesses worldwide. However, in Office 2013, Microsoft recognises the alternatives from the outset, giving you the option of switching to the OpenDocument formats popularised by OpenOffice upon first launching an application.
Microsoft Office 2013 screen grab
Microsoft's native Office file formats may be standards, but Office 2013 gives you the option to switch to OpenDocument formats from the very start.

Word

You might wonder what else you could do to so long-established a text editor as Word. It's ages since Word was just a simple tool for banging out letters and bills though.
New in Word 2013 is the ability not only to save as PDF, which you could already do, but to open and edit native PDF files too. How much you can do here depends greatly on how the PDF was created in the first place. I tested it using a regular text document printed to PDF on a Mac, and it opened for editing just fine. A council refuse collection calendar, however, which had been embedded within a document, couldn't be touched.
Microsoft Office 2013 screen grab
Word opened this PDF in Protected View because I'd downloaded it from the web, but clicking Enable Editing unlocked it (click image to enlarge).
It handles font conflicts very gracefully. With neither Helvetica Neue or Cochin installed on my PC, each of which appeared in my original test PDFs, it swapped them out for Arial and Calibri respectively, without throwing up a warning dialog.
The Read Mode is perhaps the most Metro-like aspect of Word, splitting the screen in two and displaying your document contents in columns with a navigation bar to the left displaying headings, page thumbnails or search results. If you prefer, you can dispense with the columns and read straight across the display.
Microsoft Office 2013 screen grab
The Reading View makes it easier to review your work, with an interface focused more on perusing, rather than creating (click image to enlarge).
Word feels very responsive, even in this pre-release edition. Firing it up just to tap out one short letter doesn't feel quite as laborious as it once did. It's lithe enough to enable proper live previews of set styles by reformatting your document on the fly as you roll your pointer over the various style options in the Design ribbon, which is now distinct from the separate Page Layout tab.
This new-found slickness is threaded through the suite, with the cursor bar subtly sliding from one letter to the next in Word. Cell highlight sweeps to newly selected cells in Excel, rather than jumping from one to the other as you click around your sheet.

Excel

By knocking back the visual mechanics of its spreadsheet, Microsoft has made it far easier to concentrate on your work area, which now has far greater prominence. Even the sheet tabs, which are coloured with a subtle bevel, feel more functional rather than being ugly blocks on the bottom of your pages.
Microsoft Office 2013 screen grab
With less visual clutter, it's easier to focus on your work in Excel, while the redesigned page tabs are more appealing and obvious.
Excel 2013 makes it very easy to integrate data thanks to support for a broad range of data types, including XML and MySQL, the latter of which can be drawn from live database tables. If you need to import data from a website -- perhaps where it's been published in a table -- you can draw it in directly by clicking the relevant data within Office's integrated browser.
This was a little hit and miss in my tests and it was always easier to select more than I wanted, but at least you can then go on to strip out what you don't want. Grabbing less than you needed would have been more problematic.
Microsoft Office 2013 screen grab
Clicking the arrow beside an on-page element in the browser selects it for use in Excel, although here it only gives the option to select the whole page (click image to enlarge).
Novice users will welcome the ease with which you can now find your way around Excel and manipulate your data. The improved ribbon gives direct access to all of the application's common formulae. By breaking them down into colour-coded lists, it's made them easier to find too.
The real boon though is the appearance of the smart analysis tool, which pops up when you select a range of data on the active sheet. This presents relevant formatting options for the selected data in a floating panel.
Dragging your mouse across the various options, which include heat maps, data bars and sparklines, lets you preview in an instant how the results can be presented in a graphical manner, without committing to any one of them.
Microsoft Office 2013 screen grab
The Smart Analysis tool lets you see in an instant how various formatting choices will affect the presentation of your data (click image to enlarge).
If you need to go further and render them as a full-blown chart, clicking to the Charts tab gives live previews of each chart style in a floating bubble. The value of this tool alone in making data analysis more approachable and less complex can't be overstated.

PowerPoint

PowerPoint is built from the ground up for widescreen displays, as is obvious from the options in the template gallery. If you're still designing for the 4:3 generation, you can switch to that aspect ratio from the Design ribbon. Digging deeper lets you pick a range of common alternatives including 16:10 (the default is 16:9), regular paper sizes and even 35mm slides.
Microsoft Office 2013 screen grab
PowerPoint's default templates are designed for widescreen use, but if you're presenting through a different format, you can easily resize them (click image to enlarge).
The range of formatting options is truly impressive, so the chances of your audience spotting immediately that you're using one of the regular templates should be dramatically reduced.
Each slide style has a number of variants to choose from, and as with the formatting in Word and analysis tools in Excel, they're previewed on the fly as you move your mouse over each one. For example, PowerPoint temporarily applies the changes to your active slide, while moving the mouse away reverts to your original design or previews the next style.
Microsoft Office 2013 screen grab
There are plenty of templates to choose from, each with a selection of variants to help avoid your presentation looking exactly the same as any other (click image to enlarge).
There's a huge selection of vector shapes to choose from. In the unlikely event that the shape you're after hasn't been included, you can now easily make your own using the new 'merge shapes' feature. So, if you need a rectangle with an arrow coming out of it to show a process in a flow chart, you simply drag out your rectangle, drag out an arrow overlapping it and then pick Union from the Merge Shapes menu.
Alternatively, use combine, fragment, intersect or subtract to perform various exclusion tasks, depending on your requirements. Again, hovering over each one previews the result in real time.
Microsoft Office 2013 screen grab
PowerPoint arrives pre-loaded with a wide selection of vector shapes, but if the one you need hasn't been included, you can create it yourself by combining existing shapes from the library (click image to enlarge).
The presenter view gives a Metro-like behind-the-scenes layout and a grid option that gives you an at-a-glance overview of your complete presentation. The laser pointer (controlled by your mouse, rather than a real external pointer) works in this mode too, so you can point to bullets on the display screen from your presenter screen.

Outlook 2013

Outlook 2013 does a great job of pulling together all of the relevant data connected to a contact or particular message. Much has been made of the 'peak' feature that lets you hover over your calendar or contacts to see what's coming up, without opening each module entirely, but that's only half the story.
Microsoft Office 2013 screen grab
You can peek at different parts of the application for a quick look at a calendar in Outlook without opening a complete module (click image to enlarge).
Feed it your LinkedIn and Facebook details and it interrogates your contacts on each network to pull out postings from the senders of your incoming messages. These are threaded together in chronological order, so if a contact posts two updates to Facebook, one business story to LinkedIn, and then a couple of photos to a Facebook album, you'll see each in turn.
Helpfully, these are all hidden inside a collapsible panel, so they shouldn't distract you. You can also add contacts to your social networks directly if they aren't already in your friends lists.
Microsoft Office 2013 screen grab
With Facebook and LinkedIn integrated, Outlook makes it easy to keep tabs on your contacts' social postings (click image to enlarge).
Working with a widescreen display really gives Outlook room to breathe, but it collapses in a very logical and manageable way when confined to smaller windows, which is good news for anyone planning to buy the ARM edition. A reading view shrinks the sidebar so that your mailboxes pop out when needed, rather than being permanently on display. You can thread conversations so that only the most recent post appears in your inbox.
Microsoft Office 2013 screen grab
Outlook reduces very gracefully, thanks to various options for compressing and combining on-screen elements (click image to enlarge).

Office 2013 overall

There's no single killer feature in Office 2013. The touch-optimised interface will only be of interest to tablet users. Previous editions had something new to shout about such as the arrival of the ribbon and XML file formats in Office 2007, OneNote in Office 2003 and Office Assistant (RIP), which seemed like a good idea in Office 97 (but isn't missed).
What you do get is an altogether more rounded, mature and efficient suite. Microsoft should be congratulated for creating so complex and lively a bundle of applications that is so responsive. Live previews of document formatting in Word, and data visualisations in Excel, are precisely the kind of feature that would have the potential to slow your PC to a crawl if not handled well. Not so here.
Microsoft Office 2013 is an altogether more pleasant working environment than its predecessors. If I were to reach for an analogy, it's like someone has come in and knocked down the walls in your real-world office, creating a more roomy, brighter environment in which it's easier to collaborate with colleagues. This is thanks to a refreshed interface and deep online integration.
Were it to ship today in its current state, I'd have little reservation in recommending it right away. It will be interesting to see how far Microsoft goes in further refining the code between now and its release, the date for which has yet to be confirmed.

Windows Blue leaks with side-by-side apps, teeny tiny tiles



Windows Blue, the upcoming version of Microsoft's Windows 8 platform, has leaked online according to reports, giving us a teasing glimpse of what to expect from this software sequel.
The build has been made available on file-sharing sites, the Verge reports -- though as always we'd recommend waiting for Microsoft's official update rather than sticking a half-baked, leaked loaf of software into your computer's processing oven.
New features reckoned to be on board are much smaller live tiles on the Start screen, as you can see in the leaked screenshot above, which was one of several posted to winforum.eu
For my money this view looks a lot more attractive than the restrictive grid Windows 8 customers are currently lumbered with, and mirrors the move from Windows Phone 7 to Windows Phone 8, when Microsoft decided smart phone owners are grown-up enough to resize homescreen tiles if they choose.
More settings options from the Start screen are also said to be part of the upcoming version, as well as the power to give two apps equal chunks of screen real-estate in a side-by-side view -- handy for multitasking.
A new version of Internet Explorer is also expected to be part of Windows Blue, as well asrefined touch-sensitivity.
It's fair to say that Windows 8 hasn't been a roaring success so far, but perhaps some nifty new software features will perk up the platform, and convince those using older versions of Windows to upgrade.
Are you using Windows 8? Or are you perfectly happy with your current operating systemthankyouverymuch. Let me know your thoughts in the comments or on our Facebook wall.

Ghanaian university to launch first space satellite.



SatteliteThe All Nations University College in Koforidua will soon launch its first space satellite, called “CANSAT” built by the Intelligent Space System Laboratory of the university.
Dr Samuel Donkor, President of the university, announced this at a two-day workshop on space science technology, organized by the University in Koforidua to sensitize prospective students who wish to pursue a programme in Space Science and Satellite Technology.
He said the University College introduced the Space Science and Satellite Technology programme last year and less than one year the department had been able to built the first space satellite yet to be launched.
Dr Donkor gave the assurance that the university would strive to maintain leadership in higher education by the introduction of courses that are demand driven.
Dr Ashievi Kofi, Director of Space Science Ghana, who was a resource person, stressed on the importance of science and technical education.
He said the programme would help to minimize dependence on importation of human resources on space and satellite technology.
Dr Ashievi said space science technology had contributed significantly to the economic development of some developed countries and urged the government to make financial commitment to it because its benefits are enormous.
He said since education was considered the key to effective development strategies, science and technical education must be the master key that could alleviate poverty, promote peace, conserve the environment, improve the quality of life and help achieve sustainable development.
Dr Ashievi said science and technology were perceived globally as major tolls for rapid social and economic development and Ghana could not run away from it.
He said the industrialized countries of the world applied science and technology to develop their economics and mentioned China, South Korea, India, Malaysia and Singapore as notable examples.
Dr Ashievi said some few countries followed their footsteps and had also successfully applied science and technology to transform their economies.
Mr Mamfred Quarshie, Director of Intelligent Space System Laboratory of the All Nations University, said the lab was set up as an educational project that enables the integration and collaboration among engineering and science careers, as well as encouraging team work.
He said the first step in the establishment of educational projects was the CANSAT program which is a small “satellite”, with all components, such as sensors, actuators, and GPS, housed inside a 350-ml can.
Mr Quarshie said CANSAT provides an affordable opportunity for educators and students to acquire basic knowledge of space engineering and to experience engineering challenges in building a satellite and it is launched by a rocket or balloon and released in the air.
He explained that the CANSAT project is aimed at giving students practical training in the development of an educational satellite and are able to conceptualize the mission, plan and design as well as build and test their products on the ground, charge and improve their CANSAT prototypes.
Mr Quarshie said their activities had enabled them to establish international collaboration networks of contacts in the international space education and participated in international competitions.
He said the lab was working hard to establish a Satellite Ground Station for research purposes that would enhance both institutional and industrial activities in the sub-region and also to design, build and Launch a 3 Kg CubeSat into orbit by 2016.
Mr Quarshie commended the Space Science Centre Ghana, Kwame Nkrumah University of Science and Technology and other international organizations for their support.
The Omanhene of New Juaben Traditional Area, Professor Oti Boateng, said it was clear that the exploration of the outer space bring enormous benefits both to the developed and developing countries.
He was however worried about whether developing countries battling poverty, poor health care, maternal mortality, low efficient power generation, inefficient water supply and many more other developmental challenges would invest  in space science.
According to Daasebre Oti Boateng developing countries such as Ghana stands a chance of benefiting from space science and satellite technology by way of building capacity in the area of agriculture, territorial monitoring, national security, health and environmental management.

Google has gotten the green light for the first expansion of Google Fiber, the Internet and video service the Web giant offers to the twin cities of Kansas City.
Google announced today that the Kansas City suburb of Olathe, Kan., (population 125,000) would be getting access to the high-speed Internet service after the Olathe city council approved the company's service roll-out proposal. Google, which didn't offer any launch specifics, said it was also poised to launch service in other locations.
"We think that Fiber and widespread Internet access will help to create jobs, grow local businesses, and make Olathe even stronger as it grows," Rachel Hack, a Google Fiber community manager, wrote on the company's fiber blog. "Hopefully, this is the first of several announcements that we'll be able to make about bringing Google Fiber to additional cities in the KC metro area; so stay tuned."
The expansion comes less than nine months after Google launched its 1-gigabit-per-second broadband service in Kansas City and unveiled a new interactive television service called Google Fiber TV. Google offers three packages, including the high-end $120 a month for the Gigabit and Fiber TV service package, $70 for 1Gbps broadband only, and the cost-free but limited-time service of 5Mbps download speeds and 1Mpbs uploads.
For an introductory period, people who sign up for the two services won't have to pay the $300 construction fee.

How to Install and Configure Microsoft DNS Server


Installing Microsoft DNS

Use the following steps to install DNS on your Windows NT 4.0 Server:
  1. Click the Start button, point to Settings, and then click Control Panel. Double-click the Network icon, and then click the Services tab.
  2. Click Add, select Microsoft DNS Server from the Select Network Service dialog box, and then click OK.
  3. Type the location of your Windows NT source files, click OK, and then click Close.

    NOTE: If you have any service packs installed, you will need to re-apply your service pack before restarting your computer.
  4. Restart your computer.

Configuring Microsoft DNS

Gathering Information: 

Before you actually begin configuring the DNS server, there is some basic information you will need. Some of this information must be approved by Internic for use on the Internet, but if you are configuring this server for internal use only, you can then decide what names and IP addresses to use. You will need:
  • Your domain name (must be approved by Internic)
  • The IP address of each server for which you wish to provide name resolution
  • The host names of each of the servers in step above
NOTE: The servers in the step above may be your mail servers, any public access servers, FTP servers, WWW servers, and so on. 

For example, use the following information (substitute your actual information where appropriate): 
   Domain Name: <Domain.com>
   Servers:   192.168.50.11   <Mail1.domain.com>
              192.168.50.12   <Ftp1.domain.com>
              192.168.50.12   <WWW.domain.com> (notice the same IP
                               address)
              192.168.50.15   <DNS1.domain.com>
    

Creating Your DNS Server: 

Using the information above, configure your Microsoft DNS server by doing the following:
  1. Click the Start button, point to Programs, point to Administrative Tools, and then click DNS Manager.
  2. From the DNS menu, click New Server.
  3. Type the IP address of your DNS server in the Add DNS Server dialog box (192.168.58.15 in the example information), and then click OK.
NOTE: It is not necessary to restart the DNS server for changes to your zones to take effect. All that is required is for the server data files to be updated using the following step:
  • In DNS Manager, right-click your DNS server, and click Update Server Data Files.
Creating Your Reverse Lookup Zone: 

Some applications use a reverse query to a DNS server to find the host name of a host when it has the IP address of the computer. You must configure a reverse lookup zone to provide this capability. 

NOTE: Reverse lookup zones may not be necessary in your network, but it is recommended that one be present. NSLOOKUP run on the DNS server will fail if no reverse lookup zone is configured. 

To create a reverse lookup zone, perform the following steps:
  1. In DNS Manager, right-click your DNS server, and then click New Zone.
  2. Click Primary from the "Creating New Zone for" dialog box, and then click Next.
  3. The Zone Name is derived from your IP network address. In the example information, the Zone Name is 58.168.192.in-addr.arpa. Type your reverse zone name (the least significant part of the IP address, and work toward the most significant part of the address). For example: 
       If your network ID is:         Then your reverse zone is:
    
       10.0.0.0                       10.in-addr.arpa
       130.20.0.0                     20.130.in-addr.arpa
       250.30.203.0                   203.30.250.in-addr.arpa
          

    NOTE: The syntax of the reverse lookup zone is imperative to its operation.
  4. After you type the reverse lookup zone name, press Tab and the reverse lookup zone file name will automatically fill in using the zone name in step 3 appended by ".dns" (without the quotes).
  5. Click Next, and then click Finish.
Creating Your Forward Lookup Zone:
  1. In DNS Manager, right-click your server, and then click New Zone.
  2. Click Primary Zone, and then click Next.
  3. Type the Zone Name for your DNS domain. This is the domain name that is registered with Internic (<Domain.com> in the example).
  4. Press Tab, click Next, and then click Finish.
When you have created the forward lookup zone, you should see three records automatically created in that zone: the NS record, the SOA record, and an A record. If you do not have all three of these, you may want to verify that your DNS settings in your TCP/IP properties are configured correctly (click the Start button, point to Settings, click Control Panel, and then double-click the Network icon). 

NOTE: The A record will only be created if the zone name matches the domain name. 

Adding Host Records to Your Forward Lookup Zone: 

The A record for your DNS server should have been automatically created. However, DNS Manager does not automatically create the PTR record in the reverse zone for the DNS server. The simplest way to correct this is to use the following steps:
  1. Right-click the A record for your DNS server, and then click Delete Record.
  2. Click Yes in the confirmation dialog box.
  3. Right-click your forward zone, <Domain.com>, and then click New Host.
  4. Type the host name of your DNS server and the IP address.
  5. Click Create Associated PTR Record to enable it and click Add Host.
  6. Click Done.
NOTE: Repeat steps 3-5 above for all of the servers that you want to add to your DNS domain. 

To verify the PTR records are created successfully, right-click the reverse lookup zone 58.168.192.in-addr.arpa, and then click Refresh.

Configuring Other Record Types

A DNS server can be responsible for several different record types. Some of them include, but are not limited to the following: A, CNAME, HINFO, MX, NS, and SOA. For details on these and other record types, please refer to the DNS white paper mentioned earlier in this article. 

Creating A CNAME Record: 

A CNAME record allows you to use multiple names for the same IP address. This way, you can have users access the same server for separate functions, such as FTP1.domain.com and WWW.domain.com. Before you can create the CNAME record, you must first have an A record, as described earlier. 

To create a CNAME record, perform the following steps:
  1. Right-click your forward zone, <Domain.com>, and click New Record.
  2. Select CNAME Record from the Record Type list box in the New Resource Record dialog box.
  3. Type an alternate name for access to this computer. For example, in the sample information earlier in this article, WWW is an alternate name for FTP1.domain.com.
  4. Type the original host name in "For Host DNS Name." For example, <FTP1.domain.com>.

    NOTE: It is important to use the fully-qualified domain name (FQDN) for the originating host DNS name.
  5. Click OK.
Now when your users make a query for either of these host names, your DNS server will return the same IP address. 

Creating an MX Record: 

An MX Record is a Mail Exchange record that points mail programs to your mail servers. To create an MX record, perform the following steps:
  1. Right-click your forward lookup zone, <Domain.com> and then click New Record.
  2. Select MX Record from the Record Type list box in the New Resource Record dialog box.
  3. The Host Name (Optional) field is used for the host name of the mail server. However, if you want users to be able to send mail to your domain using the format USER@Domain.com, then leave the Host Name field blank. NOTE: If the MX record contains the hostname, sending mail to user@domain.com may not work. There are three ways to resolve this. First, remove the hostname from the MX record as described in step 3. Second, after the MX record is created with the hostname, create an "A" record for the domain that has no hostname. Third, delete the existing MX record and re-create as described in steps one through six in the Creating an MX record section of this article. 
  4. Type the FQDN of the mail server in the Mail Exchange Server DNS Name, for example, Mail.domain.com.

    NOTE: There is a trailing dot, ".", after the Mail Exchange Server DNS Name. The FQDN that is used for the Mail Exchange Server must have a corresponding A record for that domain. If the Mail Exchange Server is a different computer than the DNS Server, the DNS Server must know where to redirect the mail traffic.
  5. The Preference Number is any number from 0 to 65535. In the case of multiple mail servers, this number identifies which mail server is to be used first. The lower the preference number, the higher the priority.
  6. Click OK.
