  2. In Exchange Server 2010, you can confirm the build version with by running this command in the Exchange Management Shell: GCM exsetup |%{$_.Fileversioninfo}

  3. Thank you so much for this very useful Exchange 2007 & Exchange 2010 version numbers table. It is incredibly “not easy” to find this info. on the web and what with the instability of some Exchange 2007 updates this table is just what i needed to see. Thank you.

  4. Hi,

    firstly, thank you for the table. This really helps in keeping up with the many changes to Exchange….particualrly Exchange 2010

    regarding the last roll update 4…I found this article…..

    The rollup update has been removed & a new roll update (5) will be released in august sometime. Just thought I share this with all.



  5. Thank you for the information, it has proven very useful over the years! One thing I have noticed though – there’s an error for the version number for Exchange 2007 SP1 RU9. The number you have is, however the actual number is 8.1.393.1 – I guess you made a typo there!

  6. I so appreciate you for putting this together! Thank you!

    I was trying to get EMC installed on my local machine and every time I’d install something it would still say I needed a higher version. Once I found this site, I was able to locate exactly what I needed (a specific RU version).

  7. Hi All ,
    In my system the version is given as ” 15.1.549.20 ” but i am not sure about the Microsoft Exchange Server Name for this version .

  8. Is the 2013 CU13 + KB3184736 version really 15.0.1210.3 (the same as without the KB)? I’m guessing that is a typo and version is now higher than 15.0.1210.3.

    • Previous builds which are out of support stop being available at some point through official channels. This is why you need to keep the installation set of any build you have running in production, should you ever need it again. Try to to get an earlier build through your TAM or support channel.
