Hi All, I am trying to connect to POP3 (pop3s) on exchange server its giving javax.net.ssl.SSLHandshakeException, I understand the problem that we have to import the Certificate in client system to trust it. Our IT team (people maintaing Exchange Server) has given a certificate saying that this what they have found in the exchange server but it is mismatching, the certificate they gave and the certificate which we are getting on trying to connect is different, so I am trying to find the certificate on the exchange server but I am not understanding how they are maintained in exchange server. Can some one please help me in telling how the certificates for POP3 or Mail purpose SSL Certificates are maintained and how to export it so that I can import it into my client machine.
