Is anybody using UTM SPX mail encryption with O365? Instead on-premise Exchange?

How do you propose to make that work? Outbound mail has to flow through UTM for UTM to do anything to the traffic. I doubt you can control the outbound flow from Microsoft.
It can be done. It is fully supported by Sophos.
