Exchange 2007 - Mail Restore Problem with V-79-57344-65217
i have a problem while restoring a mailbox to Exchange 2007 SP1 with BE 12.0
BE completes backup operations of Exchange successfully, but cannot restore any mail in a mailbox.
On both BE server and Exchange server have same Exchange Management Tool version, MAPICdo is installed on Exchange server. In addition GRT is successful, during restore job selection i can see all backed up mails in a mailbox. The BE server has sufficient temporary size for Exchange restore logs
Also all steps for backing up Exchange 2007 with BE in http://seer.support.veritas.com/docs/288777.htm has done.
The error log is
Completed status: Failed
Final error: 0xe000ff00 - Unable to restore some Microsoft Exchange components because one or more of the databases are currently mounted or because the Recovery Storage Group is not properly configured. Use the Exchange System Manager to check the configuration of the Recovery Storage Group and the mount status of the databases.
Unable to restore the selected Microsoft Exchange databases because one or more of the storage group's databases are mounted. Use the Exchange System Manager to dismount all the databases for the storage group 'SG****', and then retry the job.
V-79-57344-65217 - An error occurred while completing the operation on \\exchsrv.domain\Microsoft Information Store\SG****
A failure occurred performing the post-restore operation.
I tested restore job for different mailboxes in different databases and also storage groups but the result is same. What can i do for this problem
