In an Exchange 2007 - CCR cluster environment when attempting to register storage via the Access online Exchange Server (recovery Storage Group) and entering the Exchange server name (the name of the Cluster - Virtual name) and then selecting the db, it may come up with the error message 'Unable to register storage: \\ExchangeClustername\Drive$\StorageGroupname\DBname\....\DBFilename.EDB'
This has been logged as a defect (TF00100747). Waiting for fix in a future release of Recovery Manager for Exchange.
Register this database as an Offline .Edb:
1. Copy the database you want to register to the Recovery Manager computer.
2. Start the Add Storage Wizard, click Next, and use the "Access offline Exchange database, Domino databases, or .pst files" option to register the database in question.
