The http://schemas.microsoft.com/cdo/nntpenvelope/ namespace contains a set of fields that are accessible in the IMessage.EnvelopeFields property of a Message object when it is passed to a transport event sink handling one of the NNTP OnPost, NNTP OnPostEarly, or NNTP OnPostFinal transport events. These fields are only available for messages that are still in transport, and are therefore only used when writing a transport event sink. For more information, see SMTP/NNTP Transport Event Sinks_with_CDO.
