Description: The database "First Storage Group\Mailbox Store Computer Name" cannot be unmounted because Backup is in progress.
In some scenarios, the backup application exits with an error and does not reset the bit on the storage group. When this occurs, the error that is generated is similar to the error that is generated when the backup application is still running. Therefore, waiting for the backup to finish is not an option because the backup is already stopped.
To work around this scenario, restart the Microsoft Exchange Information Store service to reset the bit. As a safety measure, we recommend that you move mailboxes to another storage group, dismount the mail stores, and then restart the Microsoft Exchange Information Store service.
