For the following reasons, you may use a disaster recovery setup by running the command, setup.exe /disasterrecovery:
  • If the Bin folder has been deleted accidentally.
  • If the MSExchange registry keys are deleted and there is no backup available of the registry.
For a successful disaster recovery, you must be sure to choose the same components for disaster recovery that are installed on the server you want to recover.


  • Make sure there is a valid backup of the databases.
  • You must mount the stores after you restart the server.
  • The disaster recovery setup replaces the directory hierarchy and the registry keys without re-adding the information to Active Directory.
Note If you are running Exchange Server in a cluster, you cannot perform a setup by using the /disasterrecovery switch. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
