TaskRequestUpdateItem Object (Outlook)
Represents a response to a TaskRequestItem sent by the initiating user.
If the delegated user updates the task by changing properties such as the DueDate or the Status, and then sends it, the associated TaskItem is received by the delegator as a TaskRequestUpdateItem object.
Unlike other Microsoft Outlook objects, you cannot create this object.
Use the GetAssociatedTask method to return the TaskItem object that is associated with this TaskRequestUpdateItem. Work directly with the TaskItem object
