Thank you for your guidance Siegfried! I upgraded to JavaMail version 1.4.3
but still getting some errors using same code as before. Log file below.. I
did remove identifying info of the server: seems like they're having some
kind of handshake problem. Maybe I'm just using the wrong port. Does client
server communication usually switch from plain text to encrypted right in
the middle of communication or should it be going over a secured port
starting out. I don't have any way of talking to Exchange server admin at
this org. log file below:
