hey guys, i have a question about exchange default recipient policies
we have 5 domains all hosted on same server, currently all 5 are i our default recipient policy. we will be deleting 98% of the users from 1 domain, and want to take that domain out of our default recipient policy. we dont want to stop mail flow from that domain, but just dont want all new users to have that email address by default. if we just untick the domain from that policy, will it effect mail flow? or just not create an email address with that domain for all new users?
i was told that someone tried unticking it before, but mailflow stopped and they dont want to untick it again.
