1.3 Overview

The Task-Related Objects Protocol defines a Task object to represent a task that the user wants to accomplish. The properties of a Task object specify the due date, assignment status, and anticipated work effort, among other things. A Task object is created in the Tasks folder of a message store. Once a Task object is created, the task can be assigned. Task assignments are made, confirmed, and updated through the use of task communications, which include task requests, task acceptances, task rejections, and task updates. The Task-Related Objects Protocol also allows a series of tasks to be generated from a single Task object with a recurrence pattern.

This protocol extends the Message and Attachment Object Protocol, as described in [MS-OXCMSG], in that it defines new properties on a Message object and adds constraints to the existing properties of a Message object.
