The Enterprise Vault system mailbox assigned to the archiving task is corrupted.
In order to resolve this issue, a new system mailbox needs to be created in the Exchange Server.
Note: The new EV system mailbox needs to be created in the same Exchange server handled by the archiving task. In an Exchange DAG environment, confirm that the Exchange database in which the new system mailbox is to be created has its active copy mounted on the Exchange Server targeted by the archiving task.
