2.2.2.3.1 PidLidTaskDueDate Property

Type: PtypTime ([MS-OXCDATA] section 2.11.1)

The PidLidTaskDueDate property ([MS-OXOTASK] section 2.2.2.2.5) SHOULD<3> be set when the client creates a reminder on an object that is neither a Task object nor a Calendar object.

Setting the PidLidTaskDueDate property allows for a more intuitive "due in" time when the reminder signals. The "due in" time is the time remaining until a Message object is due.
