I am migrating mailboxes from one MS365 tenant to another. I am following all the steps from this webpage “Cross-tenant mailbox migration – Microsoft 365 Enterprise | Microsoft Learn”. But now i am stuck. I performed the migration from the Exchange Admin site for one test mailbox and I get the error:
<code>Error: MigrationCSVRowValidationException: The migration user type for '[email protected]' is not correct. Please ensure it has RecipientTypeDetails:MailUser.
</code>
<code>Error: MigrationCSVRowValidationException: The migration user type for '[email protected]' is not correct. Please ensure it has RecipientTypeDetails:MailUser.
</code>
Error: MigrationCSVRowValidationException: The migration user type for '[email protected]' is not correct. Please ensure it has RecipientTypeDetails:MailUser.
When i check the details of the user with PowerShell I can see the RecipientTypeDetails are ‘MailUser’ for the useraccount in the target:
How to solve this? Where do I start?
