Hello,

we are migrating mailboxes from Gmail to Exchange Online.
We see that all emails were migrated, but the migration prosses finished with an error:

Unable to use primary Gmail forwarding address exception. Disallowed Forwarding Address Permanent Exception. Could not use the primary address as the forwarding address "user@keyman .com". Please select a different target delivery domain.

What does it mean and how to fix it?

Thank you!

    Hi @Anahaym

    Are you following the steps list in the official document which introduces about Migrate consumer Google Workspace (formerly G Suite) mailboxes to Microsoft 365 or Office 365

    And according to your error information above, please check that your migration file has the correct Microsoft 365 or Office 365 email address in the EmailAddress column.

    Hello Joyceshen-MSFT,

    thank you for your answer.

    the email addresses in the CSV file are correct. All email items were successfully migrated, we can see them in Exchange OWA, but migration tasks still shows status - failed, because of the error above.
