View raw as2 sent out

is there a way to view the entire raw as2 message that TN is sending out? we are trying to send a document to a partner using AS2 and are getting a Bad Request - Request Message does not contain Message ID Header.

I looked in TN and saw the ediintdata and the payload elements in the transaction log, and both appear to be fine. so how can I see the raw outbound message of how the two are being combined and sent?
