Database Cannot Be Overwritten By a Restore (0xC7FE1F46)

The solution to the Database cannot be Overwritten by a Restore error is straightforward: In Exchange System Manager, open the properties of the database, and on the Database tab, select the This database can be overwritten by a restore check box.

When the recovery storage group is initially created, this check box is selected, but after a database has been successfully restored and mounted, the check box is cleared. If you restore again to the same recovery storage group database, you must mark the check box again.
