I am currently updating our Exchange 2013/2016 Ultimate Bootcamp and while searching the web have come up with a few neat things to add to the course. One of the things I have been looking at is of course the release of Windows Server 2016 and compatibility features of Exchange 2016.
As of right now Exchange 2016 is not supported to run on Windows Server 2016. That is no surprise, but here is what I found interesting. Exchange 2016 is not supported if you have Windows Server 2016 Domain Controllers.
Here is a list of supported OS's and Supported Domain environments at the time of this posting.
Will there be support added in the future. Probably, but not sure when.
