How do I check Rollup Update version on Exchange 2007 server?

Posted by in Exchange 2007, Exchange Management Shell, PowerShell

This is one question that gets asked around many times! The article “Exchange Server 2007: Platforms, Editions and Versions” gives important information to identify the build numbers for each Rollup Updates, however, it is unclear where to look for this information.

To solve that problem, I have come up with a script which looks at Exsetup.exe version and registry entries for each Rollup Update installed…

Uh, what happened to the rest of this post?

Well, since I wrote a better script that handles both Exchange 2010 and Exchange 2007, I have removed this script. You can find new version here.
