SYMPTOMS
If the Exchange Server Message Transfer Agent (MTA) receives a native X.400 message from a foreign MTA that was sent with a File Transfer Body Part (FTBP) and the originator did not add a subject to the message, depending upon whose foreign MTA sent the message, when the message is viewed by a client, the original attachment is lost, and a zero length attachment called Att.dat is present. If the originator did add a subject, the attachment will be viewed correctly.



CAUSE
