Copying/Moving of large message fails

Question

The message I am copying is approx. 13Mb, containing a PDF attachment that makes up most of the size. I've tried tweaking params on both the Exchange IMAP4 service, and JavaMail and nothing seems to work. Below is my configuration. If anyone has run into this, or has some tips, feel free to pass them along.
Thanks,
Environment:
JavaMail 1.4
Exchange 2003 (enable fast message retrieval unchecked).
JavaMail Config:
mail.debug=false

mail.imap.partialfetch=false
mail.imap.statuscachetimeout=0
mail.imap.appendbuffersize=16384
mail.imap.connectionpoolsize=5
mail.imap.connectionpooltimeout=45000

Do you have an antivirus or firewall product that might be interposing itself
in the communication with your server?
