fetchExc - Adding server certificate to certificate store

If you use https connection (Secure=true) and Exchange server has self-signed certificate you have to add server's certificate to cacerts store.

• Export certificate from Exchange server.
  • With IE: Surf to Exchange servers login page. Double-click padlock and change to Details-view on opening Certficate-window. Click Copy to File -> Next -> Choose DER encoded -> give filename (for ex. myexch.der) and save.
  • With OpenSSL:
    • $ openssl s_client -connect exch.server.addr:443 > myexch.der
    • Press Control-D after few seconds
    • Edit myexch.der so that it starts with line -----BEGIN CERTIFICATE and ends with -----END CERTIFICATE
• Move this certificate file to your target machine.
• Import key in java keystore (default password is 'changeit'). Go to javaroot/jre/lib/security. There: ../../bin/keytool -import -keystore cacerts -alias MyExchange -file /path/to/myexch.der

Now you should be able to get messsages from exchange
