Duplicate Symantec Enterprise Vault Archives

OK so hmmm, ok my suggestion is this

1. Export the users archive to a PST and choose to delete the item out of the archive
2. Enable Orphaned Shortcut Deletion in the mailbox policy if its not already enabled
3. Do a Run Now with Shortcut Processing Only and wait for it to complete, all the shortcuts for the new archive will now have been deleted
4. Disable the user from archiving
5. Delete the entries from ExchangeMailboxEntry with something like DELETE FROM ExchangeMailboxEntry WHERE mbxDisplayName = 'my user'
6. Delete the new archive that should now be empty from the PST Export
6. Re-Run provisioning and wait for it to finish
7. manually enable the user and then select the old archive (should only be one now)
8. Import the PST file that you exported and it will re-create the shortcuts if you want it to


The Orphaned Shortcut deletion wll only delete shortcuts that belong to the archive.
So for instance if you have 10,000 shortcuts for oldArchive and 2,000 shortcuts for newArchive, and then you want to do Orphaned Shortcut Deletion, it will look at the archiveID that is enabled, and only delete shortcuts that match that archiveID but do not have entries in the database
