Microsoft Exchange clients can send messages and forms to MSMQ queues by addressing messages or forms to the label of the destination queue (using an address type of MSMQ). This address can be predefined as a custom recipient in the Exchange Address Book.
Microsoft Exchange routes the appropriate message or form to the MSMQ Exchange connector. Next, the MSMQ Exchange connector translates the Exchange message or form into an MSMQ message and sends it to the appropriate destination queue. An MSMQ-based application can then read the message, parse the contents, and act upon the contents.

Note The MSMQ queue must have a mail type ID of {5eadc0d0-7182-11cf-a8ff-0020afb8fb50}.
Because the MSMQ-based applications do not natively support the MAPI rich-text format Exchange uses, MSMQ address entries should be configured so they do not send messages in rich text.
