Access denied, Your organization does not allow external forwarding – M365

  • by

When a user want to forward emails to an external mail domain, there might be extra settings you need to change in order to allow this. Because by default this is blocked by a policy. Which, in my opinion, is a good thing. But your organization might allow this for whatever reason.

Click on the Anti-spam outbound policy (Default). And then more settings will appear.

Click on the Edit protection settings at the bottom. There you will see some extra settings like you see in the next image.

Change the setting in the dropdown menu to On – Forwarding is enabled.
