Assume that you are using Microsoft BizTalk Server. You use the Multi-purpose Internet Mail Extensions (MIME) decoder pipeline component in your own receive pipeline to receive a multi-part MIME-encoded message. In this scenario, the MIME/SMIME decoder in the MIME decoder pipeline component selects an incorrect message part as the BizTalk message body part.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
