HI, this will not work if your using POP/IMAP and also your OCS Client should be able to access Exchange Web Services via HTTPS. make sure if there's any Proxy or firewall blocking the connection. check below URL for further details. http://it-proknowledge.blogspot.com/2009/02/communicator-error-exchange-connection.html Thamara.
