We have an Exchange 2016 server running on Windows Server 2016. This is activated using the HCW and the free license Microsoft provide.
We need to rebuild and replace this server on new infrastructure, and want to build on Server 2022, to make sure our Server OSs are as up to date as possible from day 1.
Exchange 2016 does not install, nor is it supported on 2022. The latest it works on is 2016.
As Microsoft do no offer the same free hybrid license for Exchange 2019, I am unclear on what Microsoft's current guidance is on deploying a new Hybrid Exchange server in the year 2021/2022.
You would think their guidance would be to "be as up to date as possible". Whilst 2016 is in extended support, we will get no further CUs for Exchange 2016. So it feels disingenuous for them to say "Be up to date", but also, "We aren't going to let you have a free Exchange license anymore".
I'm kind of between a rock and a hard place, as the server is for management of synced objects only, so we want to deploy the latest and greatest, but don't want to pay for full Exchange!
