One of our customer is getting "javax.mail.AuthenticationFailedException: AUTHENTICATE failed" when connecting to MS Exchange 2010 IMAP server.
They are using Java Mail API 1.3.2.
They are providing the user name as 'garmin/wfmailernonprod/wfmailer.plndev' and IMAP server name is 'imap.garmin.com'.
Looks like its an shared Mail box.
The same IMAP server with same username and password is working fine in an instance where Java Mail API version is 1.3.1.
Can you please explain what is the issue here and how to resolve it?
