Microsoft has released its quarterly updates for Exchange:
- Exchange 2016 CU17.
- Exchange 2013 CU18.
It has been quiet around these updates, and they do not bring a whole lot of features.
Important to note is that the minimum Forest Functional Level (FFL) has been raised to Windows Server 2008 R2. Personally I think this is an indication that more exciting stuff is along the way, especially around Exchange 2016 (my personal expectation, don’t shoot the messenger :-))
There are schema changes in Exchange 2016 CU17, so when installing this update you have to execute the following commands:
Setup.exe /PrepareSchema /IAcceptExchangeServerLicenseTerms Setup.exe /PrepareAD /IAcceptExchangeServerLicenseTerms Setup.exe /PrepareDomain /IAcceptExchangeServerLicenseTerms
When it comes to the .NET Framework, Microsoft is working on a new .NET Framework release (version 4.7.1). The upcoming quarterly update of December 2018 will support this version of the .NET Framework.
