Javamail IMAP connection to exchange just hangs

[Moshe Bar-Nachoom]

hi,
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 https://xxx.yyy.com.
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:

Properties props = System.getProperties();
props.setProperty("mail.store.protocol", "imaps");
props.setProperty("mail.imap.auth.plain.disable", "true");
try {
	Session session = Session.getDefaultInstance(props, null);
	session.setDebug(true);
	Store store = session.getStore("imaps");
	store.connect(exchangeUrl, 443, userName, password);
// here is where it hangs, waiting for i don't know why...
	System.out.println(store);
	Folder inbox = store.getFolder("Inbox");
} catch (Exception e) {
// never gets here. no exception found.
}

The debugger prints: "DEBUG: trying to connect to host "xxx.yyy.com", 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 domain.com 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.
