3.3.5.1.3.3 Deferred Properties

When an e-mail message arrives with the deferred send properties set, the server MUST honor the deferred send time.

For a message with both the PidTagDeferredSendNumber property (section 2.2.3.2) and the PidTagDeferredSendUnits property (section 2.2.3.3) present, the server will recompute the value of the PidTagDeferredSendTime property (section 2.2.3.4) from the PidTagDeferredSendNumber and PidTagDeferredSendUnits properties during message submission.
