Hi,
I know there are some caveats (not sure what they are) when migrating all mailboxes from an Exchange on-premises solution to Exchange Online and then decommission the on-premises server.
Some documents/blog posts saying that its not doable since the user accounts have a bunch of exchange attributes that does not exist in azure ad and therefor its not a good idea to remove the exchange on-premises services, rather keep it to manage exchange related things?
What specific things is it that one cannot do? One will still utilize on-prem AD for various types of services...
If one completely can remove the exchange on-prem that would be the preferable solution for us!
