Account: 'Hotmail', Server: 'http://services.msn.com/svcs/hotmail/httpmail.asp', Protocol: HTTPMail, Server Response: 'Proxy Authentication Required ( The ISA Server requires authorization to fulfill the request. Access to the Web Proxy service is denied. )', Port: 0, Secure(SSL): No, Error Number: 0x800CCC37" BTW, I enable the authentication mode for web proxy. Any ideas ? Thanks. -Zul ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: jim@xxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
