If the RO reviewer is unable to concur with the proposed decision, the reviewer will
notify the FO via email with a written explanation for non-concurrence.
For cases requiring additional development and/or a personal conference, the FO mailbox
will be notifed via email and include detailed feedback explaining why the case does
not comply with POMS. If the FO fails to provide requested information in the prescribed
time period, the case will be returned with written feedback.
