2.2 Message Syntax

Contact objects and Personal Distribution List objects can be created and modified by clients and servers. Except where noted, this section defines constraints under which both clients and servers operate.

Protocol clients operate on Contact objects and Personal Distribution List objects by using the Message and Attachment Object Protocol, as specified in [MS-OXCMSG], and the Folder Object Protocol, as specified in [MS-OXCFOLD]. The details of how a protocol server operates on Contact objects and Personal Distribution List objects are implementation-dependent, but the results of any such operations MUST be exposed to clients in a manner that is consistent with this protocol.

Unless otherwise specified, a Contact object and a Personal Distribution List object adhere to all property constraints specified in [MS-OXPROPS] and [MS-OXCMSG].
