Exchange Support For Windows Server 2012 R2

Windows Server 2012 R2 And Exchange Support Previously Windows 8.1 and Windows Server 2012 R2 were released to the TechNet subscriber download centre.   Prior to Windows Server 2012 R2 being tested and validated by the Exchange Product Group, we had asked to pause deployments of 2012 R2 DCs into environments where Exchange was installed.

Exchange 2013 Service Pack 1, Exchange 2010 SP3 RU5 and Exchange 2007 SP3 RU13 were all released today, the 25th of February 2014.   As announced back in November the Exchange team were working to test and validate Exchange against Windows Server 2012 DCs.   That work has been completed, and the support stance has been updated on TechNet.

To prevent confusion for folks that may have read this post prior to today's updated support stance it has been heavily edited to reflect the new information.  Probably not much point showing out-dated stuff, eh?

Update 5-2-2019  – Note that with the release of Exchange 2010 SP3 RU26, Exchange 2010 is supported on Windows Server 2012 R2.

Walking The Supported Path

TechNet documents the Exchange Product Group's supported OS for each version of Exchange.  Here are the links for your convenience:

System Requirements
2007
2010
2013
2016

The support matrix for all of the Exchange versions have been consolidated into one location.

There have been a couple of posts in the TechNet forums where people have run into some issues when they have either:

  • Upgraded the OS in place to Windows Server 2012 R2
  • Tried to install Exchange 2010  onto Windows Server 2012 R2

Unfortunately there is not much that can be done to help apart from digging out backups as they are not supported options.

I didn't list Exchange 2003 as hopefully no one out there is going to be trying that with Server 2012 R2. **

Supported Operating System Platforms

The following table identifies the operating system platforms on which each version of Exchange can run. Supported platforms are identified by an X character.

Exchange Supported Operating Systems

You will note that Windows Server 2012 R2 is currently only listed as a supported OS platform for Exchange 2013 SP1 onwards and Exchange 2016.  In addition to this please also note that Windows Server 2012 R2 is listed as a supported Domain Controller for Exchange 2016, Exchange 2013 SP1, Exchange 2010 SP3 RU5 and Exchange 2007 SP3 RU13 or later builds of each.

Supported Active Directory Environments

The following table identifies the Active Directory environments with which each version of Exchange can communicate. Supported environments are identified by an X character. An Active Directory server refers to both writable global catalog servers and to writable domain controllers. Read-only global catalog servers and read-only domain controllers aren't supported.
