Title
Cannot resolve permission on the source for '': Name ' ' cannot be resolved -
Description
A customer reports an issue where archive folder(s) cannot be migrated for specific user(s). The error message displayed is: "Cannot resolve permission on the source for '<UPN>': Name '<UPN>' cannot be resolved." -
Cause
The issue stems from Microsoft's validation process, not the ODM (Online Data Migration) system. Microsoft does not recognize an email address as legitimate, ODM will not be able to process it, resulting in the migration failure.
-
Resolution
Microsoft performs a lookup of email addresses to verify their validity, a process also done by ODM. However, for the migration to proceed, these email addresses must first pass Microsoft's validation.
