Exchange Error #5.5.0 smtp;554 Failed: Malformed MIME field

Hello,
I have a user who is attempting to send emails to a supplier in Taiwan, and he keeps receiving NDRs.  Our email system currently is in a coexistence environment of 2003 and 2010 (moving all my users over to 2010 by this Monday).  The user in question is still on my 2003 server.  As far as I know he has not had issues up until recently (and we've had both servers online for almost a month).  NDR is below:


Your message did not reach some or all of the intended recipients.

Thanks - that's my thought as well, I'll have to check with the sender to see if there were any attachments.  It's never fun to tell someone that I can't fix it and it's on the other side.  Especially when the other side is in Taiwan.

It looks like the original message did have an attachment, but after the original returned email, my user sent a simple message and got the same return.
