Javamail IMAP connection to exchange just hangs

i'm trying to connect to an Exchange server in my company's HQ. The server has a web interface and this is the one I'm using to also connect (successfully) through android exchange clients - say it's
So I was trying to use the JavaMail API to connect to the exchange server using the IMAP store. When I run the code, on connection attempt, the code just hangs there. It looks frozen. Does nothing.
I also tried sniffing it out with Wireshark and it looks it goes through the handshaking process just fine. And then... nothing.
Please help. here's the code:

The debugger prints: "DEBUG: trying to connect to host "", port 443, isSSL true" and then... just sits there... doing nothing... waiting... i don't know.

The user name is as proposed by the documentations: "DOMAIN\\DomainUser\\Mail.User(Without extension)"
Thanks guys. Looking forward to your help.

Hi Moshe

Does the code terminate or sit idle? Also, I wouldn't leave the catch block empty.
It is sorta covered in the JavaRanch Style Guide.
