I was administering an Exchange 2007 installation today and needed to know what service pack it was running. The problem is that exchange does not display as a service pack, only an increase in version. A bit of googling revealed the following microsoft page that contains the version to Service pack information which i have duplicated at the bottom of this post for ease http://support.microsoft.com/?kbid=158530
Find the Version of Exchange 2007
To find out the build number of Exchange 2007, launch an Exchange Management Shell and run the following command:
Get-ExchangeServer | fl name,edition,admindisplayversion
This will then give you the build number in the form of:
