Add a non-delivery report (NDR) email address (Email Security only)
Under NDR email address, verify the tenant where the NDR email address will be created. This is where any non-delivery reports (NDRs) for undelivered journal reports will be collected, as they cannot be returned to the sender. For more information, see this article: Alternate journaling mailbox | Microsoft Learn.
If you have an NDR email address in place in your M365 tenant, it will be updated our designated email address.
Note: To keep using your current NDR email address, skip this section and configure only the journal rule.
To proceed, click Create NDR email address.

Once the NDR email address has been created, you will see a success notification and the Status will change to Active.
If the NDR email address creation fails, you can create an email manually. In this case, we cannot automatically validate your setup. Monitor the provided email address to ensure it is working properly.
Click on Not working? Configure manually.
Copy the provided NDR email address.
In the Microsoft Purview compliance portal, navigate to Solutions → Data lifecycle management → Exchange (legacy).
In the field Send undeliverable journal reports to, paste the copied NDR email address.
Click Save.
If you are still unable to create the NDR email address, please contact our support team.
