Description
How to exclude Domain Rewrite for specific recipients -
Cause
Some external applications process workflows and approvals with automated emails and require the sender’s email address to match what is configured in the application. For these applications, you can add an exclusion to the transport rules created by On Demand to prevent Domain Rewrite from occurring on these messages. -
Resolution
-
Log in to Exchange Online Admin Center and view the Transport Rules.
-
Select the Rule “BT-IntegrationPro-Out-S-Internet” and click the Edit icon.
-
Click “Add Exception”.
-
Hover over “The recipient…”.
-
Select “domain is”.
-
Add the domain for the email address you are trying to add the exclusion for.

Additional Information
When adding exclusions to an On Demand Domain Rewrite transport rule, do not delete any of the pre-configured parameters. Disabling, changing priority, or modifying transport rules incorrectly can cause Domain Rewrite to stop working.
