Can you please confirm if by SMTP Relay, you are referring to the SMTP AUTH client submission protocol that uses the endpoint smtp.office365.com? We use the term SMTP relaying to refer to messages relayed via Office 365 using an inbound on-premises connector.
It would be very compelling if at "least" on all Microsoft properties 2 way encryption would not only possible but enabled by default and seamless to the user.
For those where it would not be possible at least allow for the outbound to be sent encrypted if the Microsoft Customer so chose.
