Exchange 2016 Product Version Numbers

Updated 21 March 2017

IMPORTANT: Beginning with CU5 for Exchange 2016, .NET Framework 4.6.2 is now a requirement.

IMPORTANT: For coexistence with Exchange 2016 RTM, Exchange 2013 requires CU10 and Exchange 2010 requires SP3 UR11. Exchange 2007 cannot coexist with Exchange 2016.

To get the product version number of the currently installed version of Exchange Server 2016, open the Exchange Management Shell and run one of the following commands and the output provided will look similar to this…

[PS] C:\>Get-ExchangeServer | Format-List Name, Edition, AdminDisplayVersion

Name                : EXCH1
Edition             : Standard
AdminDisplayVersion : Version 15.1 (Build 225.42)


[PS] C:\>Get-Command ExSetup.exe | % {$_.FileVersionInfo}

ProductVersion   FileVersion      FileName
--------------   -----------      --------
15.01.0225.042   15.01.0225.042   C:\Program Files\Microsoft\Exchange Server\V15\bin\ExSetup.exe


For this example, using the number associated with “ProductVersion” from the output (15.01.0225.042)…

  • “15” in the first number group refers to the Exchange “major” version. Version “15” is either Exchange Server 2013 or 2016.
  • “01” in the second number group refers to the “minor” version installed. “01” in this case is Exchange Server 2016.
  • “0225” in the third number group refers to the “build” version installed. “0225” is Exchange Server 2016 RTM.
  • “042” in the fourth number group refers to an Exchange team internal “revision” version. “042” refers to the RTM internal revision number.

Given that information, the table below displays the product version numbers associated with each service pack and update rollup for Exchange Server 2016.

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.

NOTE: This command will not work for Exchange 2007 or older.


Lastly, this script (Get-ExchangeVersionNumber.ps1) will provide us with the version (or build) number for the Exchange products installed…

$ExServers = Get-ExchangeServer
foreach ($Server in $ExServers)
	$BuildNum = [string]$Server.AdminDisplayVersion.Major+"."+$Server.AdminDisplayVersion.Minor+"."+$Server.AdminDisplayVersion.Build+"."+$Server.AdminDisplayVersion.Revision

	"Name         : " + $Server.Name
	"Role         : " + $Server.ServerRole
	"Edition      : " + $Server.Edition
	"Build Number : " + $BuildNum


Result of running Get-ExchangeVersionNumber.ps1…

[PS] C:\Tools\Scripts>.\Get-ExchangeVersionNumber.ps1

Role         : Mailbox, ClientAccess
Edition      : Standard
Build Number : 15.0.1130.7
