Cause


This error can be observed when Enterprise Vault is trying to process the A1 queue and the Exchange server or information store is unavailable at the time.

There can be two conditions that cause this issue.

1.  A mailbox move from one Exchange server to another occurs during an Archive Task run, or after the Provisioning Task run and prior to the Archive Task run.  The Provisioning Task must be run immediately after the mailbox move and before the Archive run.

2.  A mailbox move from one Exchange Server to another occurs while mail items are still in the Archive Pending status.  
 

Resolution

To fix this issue, either move the mailbox back to its original server, or perform the following actions.


1. Cancel the pending actions by following the instructions here: 100016644
2. Re-run provisioning task to update mailbox locations.
3. Reset the Pending Shortcut Timeout to its original value, and synchronize mailbox policies including folder hierarchy and permissions.


Afterward, the mailbox archiving task should run with awareness of the mailbox's new location.


Further Reading

To avoid this problem in future Exchange migrations, the best practices for moving mailboxes from one Exchange Server to another are linked in the related documents below.
