Hi everyone I installed SSL test certificate on the front end server yesterday (this is supposed to be for the OWA http traffic only), All my POP3 users couldn't connect from home yesterday even am publishing the pop3 service through another firewall There is an error in the back end server (A fatal error occurred while creating an SSL server credential.) Do I have to remove the SSL from the front end for POP3 to work? Or is it just by accident and the actual reason is something else I should look for? Thanks for any help
