This error has been 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 has occurred during an Archive run or after the Provisioning Task and prior to the Archive Run. The Provisioning Task must be run immediately after the Mailbox move and before the Archive run.
2. A Mailbox move occurred while mail items were still in "archive pending".
1. Cancel the pending actions by following the instructions here: 000028261
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, and thus without the 2850's.
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.
