Enable automatic external forwarding

1. Open the Anti-spam settings page here: https://protection.office.com/antispam.

2. Click + Create an outbound policy.

3. Enter the Name and Description. Click the down arrow next to Automatic forwarding to expand that section. Choose On - Forwarding is enabled from the dropdown.

Note

You may have other transport rules or spam policies in place at Microsoft 365 that block external forwarding in addition to the outbound spam filtering we’ve covered here. If automatic external forwarding is still blocked after adjusting these policies, you will want to reach out to your Microsoft 365 support for assistance in finding any further blocking that has been set up in your Microsoft 365 account.

Configure forwarding

Then, you can use rules in Outlook Web App to automatically forward messages to another account . In case of Helpdesk the account is the Helpdesk auto-generated email address.
