Replacing on premise Exchange server
Hi All, We have an old hybrid 2016 exchange server on O/S 2012, it only has the administrator mailbox on it and is used as a relay for our MFC and on-premise software (email notifications etc) - all...
That process should cover it. Don't forget you get an Exchange hybrid license from Microsoft if you do decide to run the HCW. Another option to reduce the attack footprint is to use Edge Transport role for relaying rather than a full Exchange version . The last item in this FAQ has some details if you go down this route.
