To find out the version and build number of Exchange 2007/2010, you can do one of the following:
- Run the Get-ExchangeServer | fl name,edition,admindisplayversion cmdlet in the Exchange Management Shell (EMS):
- Navigate to Server Configuration in the Exchange Management Console (EMC):
This will give you the major version and service pack version numbers – in my case it major version 8 (aka Exchange 2007) and Service Pack 3.
To find out the Update Rollup version, navigate to Control Panel > Programs > View Installed updates on your Exchange Server:
