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 Contact object and the Personal Distribution List object are extensions of the Message object.
A Contact object and a Personal Distribution List object are created in the contacts-related folders, as specified in section 2.2.3.
