Hello. I have a Biztalk Application that uses a POP3 Adapter to receive emails with an XML File attached. The XML file is created by a .NET web application and attached to a mail message. Biztalk gives me this error when it gets the message…
The MIME decoder cannot find a MIME part for the specified content-type. Either there was no matching content-type or there were not enough occurrences of it.
HOWEVER, if I take the mail message that is generated, strip the attachment out and then create a new message with the same file attached Biztalk accepts the message and the Biztalk Application works properly.
In once case the attachment works, in another it fails.
