Recovery Storage Group does not exist. Please create the Recovery Storage Group and add the appropriate mailbox databases to be recovered.
On Exchange 2003, the Recovery Storage Group must be created before running mailbox restore.
The mailbox restore operation has failed.
Use System Manager to create the Recovery Storage Group and add the appropriate mailbox databases to be recovered. Ensure that the RSG databases are dismounted, and the 'This database can be overwritten by a restore' flag has been set. Run the command again.
