Exchange 2013 Product Version Numbers

Updated on 18 October 2018


  • With CU21 for Exchange 2013, .NET Framework 4.7.2 is now supported and will be a requirement with CU23 (anticipated release in Jun 2019).
  • With CU19 for Exchange 2013, .NET Framework 4.7.1 is now supported and will be a requirement with CU21 (anticipated release in Jun 2018).
  • FYI … .NET Framework 4.7.0 is not–and will not–be supported for Exchange 2013.
  • With CU16 for Exchange 2013 and newer, .NET Framework 4.6.2 is a requirement.  If you are upgrading from a CU version prior to CU16, you must upgrade Exchange 2013 to CU15 first, then upgrade to .NET Framework 4.6.2, and finally upgrade Exchange 2013 to one of the newer, supported CUs.

To get the product version number of the currently installed version of Exchange Server 2013, open the Exchange Management Shell and run this command…

Get-Command ExSetup.exe | % {$_.FileVersionInfo}


The output provided will look similar to this…

ProductVersion   FileVersion      FileName
--------------   -----------      --------
15.00.0995.029   15.00.0995.029   C:\Program Files\Microsoft\Exchange Server\V15\bin\ExSetup.exe


For this example, using the number associated with “ProductVersion” from the output (15.00.0995.029)…

  • “15” in the first number group refers to the Exchange version. Version “15” is Exchange Server 2013.
  • “00” in the second number group refers to the service pack that is installed. “00” is Exchange Server 2013 RTM and Service Pack (SP) 1.
  • “0995” in the third number group refers to the update rollup that is installed. “0995” is Exchange Server 2013 Cumulative Update (CU) 6.
  • “029” in the fourth number group refers to an Exchange team internal revision number. “029” refers to a version of a specific CU (i.e. CU2-v2). There might be multiple versions of the same CU.

Given that information, the table below displays the product version numbers associated with each service pack and update rollup for Exchange Server 2013.

NOTE: Unlike with previous of Exchange, if we run “Get-ExchangeServer | FL Name,Edition,AdminDisplayVersion” (as instructed in several MS articles) the CU version that is installed is now properly displayed.

The Cumulative Update (CU), Rollup, and Service Packs you have running on the on-premises server should also not be overlooked. Under normal circumstances we support you being no more than two updates behind the currently released update for Exchange; however, for hybrid environments, we are stricter and you should not be more than one build behind. If the latest update is Exchange 2013 CU9, then you must have either Exchange 2013 CU9 or CU8 to be considered in a supported state. We are stricter with our hybrid requirements because of how tightly the on-premises and Exchange Online environments will be coupled together. For more information on our available updates please go here.


Additionally, you can run the following two commands from an elevated PowerShell console on an Exchange server to get the current Exchange Product ID that is installed…

([ADSI]"LDAP://CN=First Organization,CN=Microsoft Exchange,CN=Services,CN=Configuration,$RootDSE").msExchProductID

NOTE: In the command above, the value “CN=First Organization” may vary for your environment.
