I visited a customer recently who was running Exchange Server 2007 but could not tell me which service pack was installed. Not a problem, its just a quick powershell command to find out.
[PS] C:\>Get-ExchangeServer | fl name, *version* Name : EX2007 AdminDisplayVersion : Version 8.2 (Build 176.2) ExchangeVersion : 0.1 (8.0.535.0)
The AdminDisplayVersion attribute is the one to look at.
You can look up the complete list of Exchange version numbers here.
This is the new page at Microsoft for Exchange builds:
THE LINK NO LONGER WORKS
goto control panel and select the exchange 2007 and click on the remove button, it will open the exchnage server mentainence mode & it lists the Exchnage server SP1 or Sp2 or SP3 .
