Plugin version :: 1.026

Jenkins version :: 2.73.3

I have installed Poll-mailbox-trigger-plugin on my jenkins server. we are using MS-Exchange as a mail server.

On clicking Test Connection we are getting following exception:

Connecting to the mailbox...
Error : javax.mail.MessagingException: No login methods supported!;
nested exception is:
com.sun.mail.iap.ProtocolException: No login methods supported!

and sometime
