Auto Forwarding to External Emails Not Working with Exception Added to Allow It
- Hm, seems I overlooked/misread the drop message above - this is caused by the Remote domain settings, not the Outbound policy controls. Check the Default remote domain settings, or better yet, create a separate object:
New-RemoteDomain blabla -DomainName blabla.com
Set-RemoteDomain blabla -AutoForwardEnabled $false
I disabled my Exchange Rule completely, that is set to block forwarding to external emails, and email forwarding still failed with the same error so it is not this policy causing the issue.
If it's not exchange, how are we to find what's blocking this if the error doesn't tell us? In Defender > Policies and Rules >Threat Policies > Anti Spam, if I create a new Outbound there is nothing about internal or external forwarding. Only external forwarding fails. Also, the "Sender" is not possible to choose as a user since the mailbox is a shared mailbox, all forwarded emails show the sender as the original sender which is different for every email.
I also changed the global policy to On and still all emails forwarded externally fail with the same error.

(why would one have -AutoForwardEnabled $false - it makes sense in this case to have it $true)
- Wooo that worked like a charm. I created a new one specifically for the recipient domain and now emails are be forwarded. Thank you!

You can also create a Mail Contact with external email address. Forward to the contact. Then Antispam rule should be enough
