Exchange Replication Service VSS Writer failed restoring a backup because a prohibited attempt was made to add additional restores to a previous restored backup set where database recovery was already performed (perhaps unsuccessfully). The restored backup set is described in the existing restore environment document '%1'.

Additional restores to this database or location will continue to fail until the remnants from the previous restored backup set have been manually cleaned up.
