3.1.4.2.3 Modifying a Personal Distribution List

When modifying a Personal Distribution List object, the client opens a Message object as specified in [MS-OXCMSG] section 3.1.4.1, modifies any of the properties in accordance with the requirements in [MS-OXCPRPT] and in section 2 and section 3.1.5.8 through section 3.1.5.11 of this specification, and saves the Message object as described in [MS-OXCMSG] section 3.1.4.3.

It is possible that personal distribution lists contain circular references to one another. Such circular references SHOULD be avoided but are permitted under this protocol, and the client MUST be able to handle circular references.
