The Exchange Server must be online and running before you can restore a database.
The databases must exist on the Exchange Server.
Restoring deleted databases is not supported.
SnapCenter schedules for the database must be suspended.
The SnapCenter Server and the SnapCenter Plug-in for Microsoft Exchange Server host must be connected to the primary and secondary storage that contains the backups you want to restore.
