I’ve been lookin at ways to reduce the risk of people setting up email auto-forwarding to external domains in exchange online.  Appears to be a few ways and this site offers a few good options Block Email Auto-Forwarding to External Domain (admindroid.com)

However they all seem to offer a solution after the forwarder is setup.

Is there a way to prevent someone from even creating one in outlook to start with?  For example I create a rule that forward everything to my gmail but before I can save it I get error saying against company policy and it blocks the creation of the rule in my outlook client in the first place.
