This issue may occur when one of the following causes is true.

Mailbox store recovery cause 1

The mailbox store was not added to the Recovery Storage Group.

Mailbox store recovery cause 2

The mailbox store that you are trying to restore is not configured as part of an existing Recovery Storage Group.

Public folder store cause 3

This cause may occur when one of the following is true:

1. The storage group that you try to restore contains one or more public folder stores.
2. You try to restore a single public folder store instead of a storage group.

To work around this issue, use one of the following methods.

Workaround for mailbox store recovery cause 1

To work around this issue, you must first add the mailbox store that you want to the Recovery Storage Group. For additional information about how to add a mailbox store to a Recovery Storage Group, see the "More Information" section.

Workaround for mailbox store recovery cause 2

To work around this issue, delete the Recovery Storage Group and try the restore operation again.

By default, if you delete the Recovery Storage Group, the information store restores the data to the original mailbox store instead of to the Recovery Storage Group. To delete the Recovery Storage Group, follow these steps:

1. Start Exchange System Manager.
2. Expand Administrative Groups, expand the administrative group that you want, and then expand Servers.
3. Click the server that you want, and then right-click Recovery Storage Group in the right pane.
4. Click Delete, and then click Yes.

Workaround for public folder store cause 3

There are two methods that you can use to work around public folder store cause 3.a or public folder store cause 3.b.

Method 1: Delete the Recovery Storage Group

By default, if you delete the Recovery Storage Group, the information store restores the data to the original mailbox store instead of to the Recovery Storage Group. To delete the Recovery Storage Group, follow these steps:

1. Start Exchange System Manager.
2. Expand Administrative Groups, expand the administrative group that you want, and then expand Servers.
3. Click the server that you want, and then right-click Recovery Storage Group in the right pane.
4. Click Delete, and then click Yes.
5. Try the restore operation again.

Method 2: Turn on the Recovery Storage Group override registry value

If you do not want to restore data to the Recovery Storage Group and you do not want to delete the Recovery Storage Group, create the Recovery SG Override value in the registry subkey, and then set the value to 1. When you create this value, the information store ignores the Recovery Storage Group during a restore operation.

To create and configure the Recovery SG Override registry value, follow these steps.

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

1. Click Start, click Run, type regedit, and then click OK.
2. Locate and then click the following registry subkey:
   HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeIS\ParametersSystem
3. On the Edit menu, point to New, and then click DWORD Value.
4. Type Recovery SG Override, and then press ENTER.
5. On the Edit menu, click Modify.
6. In the Value data box, type 1, and then click OK.
7. Quit Registry Editor.
8. Try the restore operation again.

Important Make sure that you delete the Recovery SG Override registry value when you no longer require it.
