Java EE (Java Enterprise Edition) General Discussion

I've been trying for quite awhile to log into an Exchange 2007 mail server using JavaMail and IMAPS. It's a 2-minute task to access Unix mail, but Exchange mail servers are apparently a different animal.

Have burned many hours on this so far.

Here is the JavaMail code connecting to Exchange 2007 via IMAPS:

Properties props = System.getProperties();

props.put( "mail.imaps.auth.plain.disable", "true" );
props.put( "mail.imaps.auth.ntlm.disable", "true" );

Session session = Session.getInstance( props, null );
session.setDebug( true );

final String host = "ABCDE.mailserver.somedomain.com";
final String user = "bgates";
final String pass = "shhh";
final int port    = 993;

Store store = session.getStore("imaps");
store.connect( host, port, user, pass );  // <------------------------------------------------ fails here

Here is the JavaMail debug log:

The Exchange administrators state IMAPS is enabled on the server, and have mentioned that perhaps I have to specify a Windows network "domain" with my username string, but I've tried several username variations (below) with all yielding the same authentication error: "LOGIN failed."

Username strings tried:

1) "bgates"
2) "ABCDE.mailserver.somedomain.com\\bgates\\bill.gates"
3) "bgates@ABCDE.mailserver.somedomain.com"
4) "WINDOWSDOMAIN\\bgates"


We're dead in the water on this, hope someone can help!
