Last week I had to upgrade a few Exchange 2013 CU15 servers to Exchange 2013 CU18. In a typical scenario upgrading to a newer Cumulative Update it’s not a big deal, not even when skipping a few versions, but in this scenario most likely you will hit the following error message:
It fails during the Prerequisite Analysis with the error message
“This computer requires .NET Framework 4.6.2 (https://support.microsoft.com/kb/3151802). For more information, visit: http://technet.microsoft.com/library(EXCHG.150)/ms.exch.setupreadiness.MinimumFrameworkNotInstalled.aspx
The Exchange Server setup operation didn’t complete. More details can be found in ExchangeSetup.log located in the (SystemDrive):\ExchangeSetupLogs folder.”
Exchange Server 2013 CU18 requires the .NET Framework 4.6.2 for installation which was obviously not installed on these servers.

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 CU7, 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.
