Here some pretext to understand where we were, currently are and want to go to:
So what we have left is essentially an onPrem Exchange VM for creating new AD Users with a remote mailbox in Exchange Online.
We're in the process of moving all possible VMs to Azure PaaS/IaaS (Windows Server 2019 VMs).
Where I'm stuck is that I have no route to go for Exchange Management according to this matrix: https://docs.microsoft.com/en-us/exchange/plan-and-deploy/supportability-matrix?view=exchserver-2019
Ideally, I would have an option to fully get rid of Exchange (onPrem or in Azure), but I can't find it.
What are my options to fully move forward with Forest/Domain Levels and Server 2019 VMs in Azure?
Is there anything on the horizon for us?
