2.1.1 Abstract Data Model
This section describes a conceptual model of possible data organization that an implementation maintains to participate in this algorithm. The described organization is provided to facilitate the explanation of how the algorithm 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 includes the following abstract data model (ADM) types and elements:
Mailbox, as specified in [MS-OXCMSG] section 18.104.22.168.
MessageObject, as specified in [MS-OXCMSG] section 22.214.171.124.
