Before you perform the restore process, you must dismount the Exchange databases that you want restored. If any of the databases that you attempt to restore are still mounted, the restore process will fail.

Note When mailboxes and public folders are dismounted, they are inaccessible to users. Because Exchange 2000 supports multiple storage groups and multiple mailbox and public folder stores, you need to dismount only the databases that are being restored from backup.

To dismount the mailbox and public folder stores that you are restoring

1. Click Start, point to Programs, point to Microsoft Exchange, and then click System Manager.
2. In Exchange System Manager, in the console tree, expand Administrative Groups (may be marked Servers), and then expand the administrative group (server) that contains the server that has the storage groups you want to restore.
3. Expand the server that contains the databases you want to restore, right-click each database contained within a Storage group and click Dismount Store (see below). You must dismount every database that you want to restore. The databases comprise both the Mailbox and Public Store, both need to be dismounted.
