So currenlty, we are using the default outbound spam policy in our security & compliance center to manage automatic forwarding, to be set to "Automatic". We currently have the issue ,that it "sometimes" blocks a domain we actually want to allow (like every 4th E-Mail gets forwarded):
I unfortunately can't see any other pattern then the policy blocking some E-Mails, because it doesn't block any specific sender or anything... Now our Admin doesn't want to set up a own policy for it, that's why I wanted to ask if there is another way to allow automatic-forwarding to this domain.
I already tried to set the auto-forwarding in exchange-online to the specific external sender as a contact, and the Domain is also on our allow-list in our spam filter.
Thank you for your help.
