Error Message

The following can be found in the AsProcess logs on the Folder Sync server.  (NOTE: By default in the ProgramData folder)

2020-05-27 21:44:12.850 [(T04) VSLLC:CustomSynch:AsProcess04:Schedule(2):SynchDb] - Mailbox status set to 'Started'! MbxIdentity(OUT): 73907

2020-05-27 21:44:12.943 [(T04) VSLLC:CustomSynch:AsProcess04:Schedule(2)] - Stopping target. Final status: Erred, Event: 10094(errSSMailboxHasBeenMigrated), Deselect Mbx? False, MbxIdentity: 73907

The original mailbox has been migrated a new mailbox but still selected for synchronizations.

Deselect the original mailbox from the All Mailboxes view and select the destination mailbox so the correct one gets synchronized from now on.  Reference the documentation on how to select/deselect mailboxes here. 

To identify both the original and destination mailboxes run the following query in the ArchiveAccelerator database. 

USE ArchiveAccelerator
SELECT *
FROM tblMailboxItemSyncMigration
WHERE DestinationMbxIdentity=73907 OR OriginalMbxIdentity=73907 --MbxIdentity from the error

The above query only shows the MbxIdentity of the mailbox.  To view this value in Folder Sync it can be found in the Job List, but also in the All Mailbox view.  Do the following to show the value for all mailboxes:

1. Go to the All Mailboxes view (Console Root -> Archive Accelerator -> Archive Tools -> All Mailboxes)

2. Right-click on any of the columns and select Column Chooser

3. Drag the Mbx Identity to a column in the view

If the issue persists after deselecting the original mailboxes from Folder Sync, or the active mailbox is in the error, then open a case with Veritas Support.
