MIcrosoft Office compatibility
Now that you know a little bit about the backgrounds of Windows 7 and Office, it's time to learn about which Office edition can be used for Windows 7. The recommended versions of Office that work with Windows 7 are 2003, 2007, and 2010. Both Office 2003 and 2007 have current updates that allow them to run fairly smoothly on the new requirements for Windows 7.
Outlook is a popular email program, especially in the business workplace where many employees connect with Microsoft Exchange. As with the Office suites, Outlook 2003, 2007, and 2010 will work on Windows 7. The older versions of Outlook, such as in Office 2000 or Office XP, may be able to run on Windows 7, but there will be several issues that you may encounter.
The main problem with using older versions of Outlook or even Office is that there may be no support for them. This is a common procedure when new products come out from a manufacturer. And while it may save you some money by keeping the older programs, you run the risk of not being able to get support. This means there are no updates for a previous version of Outlook or Office pre-2003.
This runs the risk of Outlook not working correctly and not having access to a fix or patch that had previously corrected the problem. There is also the issue with exploits that someone could use maliciously against you or others. Microsoft has been known as a target for hackers as it is a widely used operating system and program suite. Microsoft uses Windows or Microsoft Updates to implement patches or hot fixes to stop someone from using these exploits. If you're using an outdated version of Outlook or Office, you may not be able to get these hot fixes for that program or suite.
Currently, Microsoft is only issuing Windows updates for Office 2003, 2007, and the new 2010.
The other issue of using a previous version of Outlook is that the probability of it running correctly on Windows 7 is negligible; it may work or it may not. There are also new features in more recent versions than that of previous versions. Depending on which version of Office you have, you not even have Outlook as a feature (such as with the Student or Home editions of Office).
