Exchange 2016/2013/2010 Updates March 2017

Today, the Exchange Team released the March updates for Exchange Server 2013 and 2016, as well as Exchange Server 2010 and 2007. The latter will receive its last update, as Exchange 2007 will reach end-of-life April 11, 2017.

As announced in December updates, Exchange 2013 CU16 and Exchange 2016 CU5 require .NET 4.6.2. The recommended upgrade paths:

  • If you are still on .NET 4.6.1, you can upgrade to .NET 4.6.2 prior of after installing the latest Cumulative Update.
  • If you are on .NET 4.52, upgrade to Exchange 2016 CU4 or Exchange 2013 CU15 if you are not already on that level, then upgrade to .NET 4.6.2, and finally upgrade to the the latest Cumulative Update.

The Cumulative Updates also include DST changes, which is also contained in the latest Rollups published for Exchange 2010 and 2007.

Exchange 2013 CU16 fixes:

  • KB4013606 Search fails on Exchange Server 2016 or Exchange Server 2013

Notes:

Exchange 2016 CU5 doesn’t include schema changes, however, Exchange 2016 CU5 as well as Exchange 2013 CU16 may introduce RBAC changes in your environment. Where applicable, use setup /PrepareSchema to update the schema or /PrepareAD to apply RBAC changes, before deploying or updating Exchange servers. To verify this step has been performed, consult the Exchange schema overview.

When upgrading your Exchange 2013 or 2016 installation, don’t forget to put the server in maintenance mode when required. Do note that upgrading, before installing the Exchange binaries, setup will put the server in server-wide offline-mode.

Using Windows Management Framework (WMF)/PowerShell version 5 on anything earlier than Windows Server 2016 is not supported. Don’t install WMF5 on your Exchange servers running on Windows Server 2012 R2 or earlier.

When using Exchange hybrid deployments or Exchange Online Archiving (EOA), you are allowed to stay at least one version behind (n-1).

  • If you want to speed up the update process for systems without internet access, you can follow the procedure described here to disable publisher’s certificate revocation checking.
  • Cumulative Updates can be installed directly, i.e. no need to install RTM prior to installing Cumulative Updates.
  • Once installed, you can’t uninstall a Cumulative Update nor any of the installed Exchange server roles.
  • The order of upgrading servers with Cumulative Updates is irrelevant.

Caution: As for any update, I recommend to thoroughly test updates in a test environment prior to implementing them in production. When you lack such facilities, hold out a few days and monitor the comments on the original publication or forums for any issues.

Cumulative Update 2 for Exchange Server 2016

.Net 4.6.1 Support

Support for .Net 4.6.1 is now available for Exchange Server 2016 and 2013 with these updates. We fully support customers upgrading servers running 4.5.2 to 4.6.1 without removing Exchange. We recommend that customers apply Exchange Server 2016 Cumulative Update 2 or Exchange Server 2013 Cumulative Update 13 before upgrading .Net FrameWork. Servers should be placed in maintenance mode during the upgrade as you would do when applying a Cumulative Update. Support for .Net 4.6.1 requires the following post release fixes for .Net as well.

Note: .Net 4.6.1 installation replaces the existing 4.5.2 installation. If you attempt to roll back the .Net 4.6.1 update, you will need to install .Net 4.5.2 again.

AutoReseed Support for BitLocker

Beginning with Exchange 2013 CU13 and Exchange 2016 CU2, the Disk Reclaimer function within AutoReseed supports BitLocker. By default, this feature is disabled. For more information on how to enable this functionality, please seeEnabling BitLocker on Exchange Servers.

SHA-2 Support for Self-Signed Certificates

The New-ExchangeCertificate cmdlet has been updated to produce a SHA-2 certificate for all self-signed certificates created by Exchange. Creating a SHA-2 certificate is the default behaviour for the cmdlet. Existing certificates will not automatically be regenerated but newly installed servers will receive SHA-2 certificates by default. Customers may opt to replace existing non-SHA2 certificates generated by previous releases as they see fit.

Exchange Updates installing slow on Windows Server 2012 R2

For customers who are running Exchange on Windows Server 2012 R2, we want to make certain you are aware of a condition which can substantially increase the amount of time it takes to install Exchange Updates on this OS. Working with the .Net team, we have discovered that systems which have applied Windows Update KB3097966 can take 50% more time to install Exchange. The .Net team is working on a resolution to this and will include a fix in a future product update. In the meantime, customers who have deployed this Windows update can take a one-time action on their server before installing Exchange or a Cumulative Update to bring installation time back to normal. This procedure needs to be done once on every Exchange server running Windows Server 2012 R2. The command to execute is:

“%windir%\Microsoft.NET\Framework64\v4.0.30319\ngen.exe update”

Errors and warnings encountered running this command can be safely ignored provided the final exit status code of 0 is reported in the output.

Cumulative Update 12 for Exchange Server 2013

Exchange team released CU12 for Exchange 2013

Issues that this cumulative update fixes:
