126.96.36.199 PidTagDeferredDeliveryTime Property
Type: PtypTime ([MS-OXCDATA] section 2.11.1)
The PidTagDeferredDeliveryTime property ([MS-OXPROPS] section 2.653) contains the date and time, in UTC, at which the sender prefers the message to be delivered. This property MAY be included in the response. If the property is absent, the message is delivered as soon as possible. If it is present, the property SHOULD have the same value as the PidTagDeferredSendTime property (section 188.8.131.52).
A client sets both the PidTagDeferredDeliveryTime property and the PidTagDeferredSendTime property for deferred delivery of a message before submission.<3>
