Is the default ban on external forwarding for ATP customers only?

Occasional Contributor

Hi, I've seen contradictory documentation about the new setting that will automatically block external forwarding of mail from a user mailbox (see https://www.vansurksum.com/2020/08/25/microsoft-is-making-changes-related-to-automatic-email-forward...).  Is this just for customers with ATP or will it impact deployments that are using only EOP?

@Arindam Thokder Thanks! Is there a way to easily audit what mailboxes already have rules which forward mail externally?

@Arindam Thokder Is this what I get for living in powershell & not the GUI?  ;)  Thank you.
