I would have thought he way to do this is to use your own host for outbound
mail, allowing you to archive copies of it however you want, rather than have a
third party relay mail through you. You can certainly prevent connections out
to other mail hosts so that your server cannot be bypassed inside your
network/VPN.
Obviously when out on the open Internet there would need to be a system on
Microsoft’s side for these sorts of clients, but wouldn’t it be simpler to say
“Hey, you’re a valid 0365 account, but you are only authorized to used
[Corporate mail server]?
Using the corporate mail server as a relay struck me (and still strikes me) as
the bassackwards way to do this, but I assume I am missing something in there.
