Provide me a java class to connect to a Exchange Mail Server throw imap

I'm java programmer but i just can't connect successfully to a Exchange Mail Server. I got this error: No login methods supported! I'm using the solution in [login to view URL] In second answer, but I still get the same error. I'm using a customized version of this project. [login to view URL] And my problem is in this class: [login to view URL] in method connect. It catch the MessagingException with the error provided. This work works ok with gmail accounts, but not with Mail Exchange Servers ___ Credentials aren't provided because my customer has not public ip for his mail server. First one in prove me he has a solution (this request is kind of urgent), throw teamviewer or [login to view URL], will be paid one or two hrs to implement the class in my project. Thank you.
