Error Moving mailbox from DBs to another
Hello I have an issue moving mailbox from database to another and when try to check the reports I found the following error : Error: MapiExceptionUnknownUser: Store Integrity check operation fail...
i have same issue
The issue is some time after disable a mailbox and enable it again it remain disabled
To resolve run the below command to update the database:
Update-StoreMailboxState -Database “db_name” -Identity “mailbox_guid”
Then rerun the migration process
