2.2 Message Syntax

A rights-managed email message consists of a set of Message object property constraints, including a Use License, and an attachment containing an encrypted version of the original message.

The protocol defines several data formats to support rights-managed email messages in addition to those specified in [MS-DTYP].

Unless otherwise specified, rights-managed email Message objects adhere to all property constraints specified in [MS-OXCMSG]. A rights-managed email Message object can also contain other properties, but these properties have no impact on this protocol.<1>
