Find out Exchange 2007 / 2010 Version, Service Pack and Update Rollup

Microsoft Exchange Server Version number is often displayed in a numeric format, e.g Version 8.1 (Build 278.2). It may not look very meaningful at first but it’s easy enough to decode these numbers.

Find Exchange version

You can find out your Exchange 2007 and 2010 version either using following methods:

Exchange Management Shell

• Run: GCM exsetup |%{$_.Fileversioninfo}

Check ExSetup.exe version

Navigate to your exchange installation Bin directory (e.g. C:\Program Files\Microsoft\Exchange Server\Bin) and check ExSetup.exe file properties. Version will be listed in Version or Details tab.

Exchange management Console

• Open EMC > Help > About Exchange Server

Following two methods are also often used, but can be quite unreliable. Although they display major versions correctly, Update Rollup can be inaccurate. I would recommend using one of the above methods

Exchange Management Shell

• Run: Get-ExchangeServer | fl name, edition, admindisplayversion

Exchange management Console

• Open Server Configuration and check Version column

Version Number

Let's take our first example: Version 8.1 (Build 278.2)

• First number represents Exchange version: Version 8 is Exchange 2007, Version 14 is Exchange 2010
• Number after a dot represents Service Pack: 1 for SP1, 2 for SP2, etc
• Build number changes after installing Update Rollups (more info below)

So Version 8.1 (Build 278.2) is Exchange 2007 Service Pack 1 Update Rollup 2
