3.1.1 Abstract Data Model
This section describes a conceptual model of possible data organization that an implementation maintains to participate in this protocol. The described organization is provided to facilitate the explanation of how the protocol behaves. This document does not mandate that implementations adhere to this model as long as their external behavior is consistent with that described in this document.
This protocol uses the abstract data model that is specified in [MS-OXCMSG] section 3.1.1 with the following adaptations:
The Task object and the task communications are extensions of the Message object.
A Task object is created in the Tasks folder, which is a Folder object, unless the end user or user agent explicitly specifies another folder.
