Prevent autoforwarding
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.
- DiehlPCopper ContributorIf you are using EOP you can active a rule in the Anti-spam outbound policy to prevent it.
Also there was a blog article a couple of years ago https://techcommunity.microsoft.com/t5/exchange-team-blog/all-you-need-to-know-about-automatic-email-forwarding-in/ba-p/2074888 - There are no such controls for Outlook, but on the admin side you can prevent such rules from working.
