Adobeconnect outlook add-ins version 3.5 cannot establish the connection with the server

i am using outlook 2010 and i have installed the outlook add-ins ver3.5 to my laptop. i was trying to login the server through add-ins with my login details. But it popup"cannot establish the connection to server, please check your server address and account", the server i am using is "intercall-apac.adobeconnect.com". Just want to know is there any port should be opened on the firewall?
