How to decommission on-premises exchange servers and move completely to O365
We are currently using Exchange server 2013 in a hybrid setup with centralised mailflow through our on-premises servers. All our mailboxes are in O365. Following outbound connectors exist in O365:-...
You will need to install the mailbox role. You can't install Exchange 2016 without it. Exchange 2016 consolidates roles from previous versions into only two roles which are Mailbox and Edge Transport.
At the moment we will be keeping 1 exchange 2013 server (may upgrade later to 2016 and license it using HCW as per your advise). So I guess I will need both CAS and mailbox roles on it?
So is there no way to get rid of MTA on it?
