Fatal error TooManyMissingItemsPermanentException has occurred.

This error occurs when there are too many bad items encountered during a mailbox migration. By default the "BadItemLimit" is set too 0 - which means that if ANY corrupted items are found during the migration it will fail.

In order to circumvent this we can specify the "BadItemLimit" switch along with the New-MoveRequest command:

New-MoveRequest -Identity <user-mailbox> -TargetDatabase <mailbox-database> -BadItemLimit 100
