Receovery Storage Group cannot be removed - says users are using mailbox store

If you do a mailbox restore and use a recovery storage group, and then add users subsequently, for some reason - they are stored in the recovery storage group and not the primary information store.  And then that means you can't delete the recovery storage group because it says:

One or more users currently use this mailbox store. These users must be moved to a different mailbox store or be mail disabled before deleting this store.
