Notes:

  • Exchange 2016 CU1 includes schema changes, and Exchange 2013 CU12 may introduce RBAC changes in your environment. When applicable, make sure you run PrepareSchema /PrepareAD before deploying. To verify this step has been performed, consult the Exchange schema overview.
  • If you have deployed KB3097966 on your Exchange server running on Windows Server 2012 R2, you may want to manually recompile the .NET assemblies before upgrading Exchange to significantly speed up the process. To accomplish this, run the following on every Exchange server on Windows Server 2012 R2:
    “%windir%\Microsoft.NET\Framework64\v4.0.30319\ngen.exe update”
    Don’t get upset by the messy output and any error messages; if the result of this command shown in the output is ‘0’ you’re good to go.
  • Be advised .NET Framework 4.6.1 is still not supported; make sure you don’t install this .NET update on your Exchange servers.
  • The Windows Management Framework (WMF)/ PowerShell version 5 is not supported. Don’t install this on your Exchange servers.
  • When using Exchange hybrid deployments or Exchange Online Archiving (EOA), you are required to stay current.
  • 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.
  • Rollups are cumulative per service pack level, meaning you can apply the latest Rollup for Service Pack X to a Service Pack X installation.

Finally, as always for any Hotfix, Rollup, Service Pack or Cumulative Update, I’d recommend to thoroughly test this in a test and acceptance environment first, prior to implementing it in production. When you lack such facilities, hold out a week or two and monitor the comments on the original article or TechNet forum for any issues.

 

One thought on “Exchange Updates – March 2016

  1. Michel – After upgrading to CU12, we cannot search our Exchange mailboxes (calendar, contacts, or e-mail). Does this surprise you?
