How to Set the Recovery Storage Group Override Registry Key

  • Article

 

If you restore mailbox stores without creating a Recovery Storage Group, the data will be restored directly to the original mailbox stores, as in previous versions of Exchange. If you already created a Recovery Storage Group, you can restore directly to the original mailbox stores if you set the override registry key.

Note

Incorrectly editing the registry can cause serious problems that may require you to reinstall your operating system. Problems resulting from editing the registry incorrectly may not be able to be resolved. Before editing the registry, back up any valuable data.

Procedure

To set the Recovery Storage Group Override registry key

  1. Start Registry editor (regedit).

  2. In Registry Editor, navigate to the following registry key:

    HKLM\SYSTEM\CurrentControlSet\Services\MSExchangeIS\ParametersSystem

  3. Create a new DWORD value Recovery SG Override = 1. After this key has been set, you can restore mailbox stores to their original locations, even though the Recovery Storage Group exists.
