hi list, i know, there are many writings about outlook web access and how to configure it with transparent proxy. but i still have problems :-( I configured my proxy like this: http_port 80 httpd_accel_host internalmailserver httpd_accel_port 80 httpd_accel_single_host on httpd_accel_with_proxy on httpd_accel_uses_host_header off I can connect from outside and get my basic authentication from my internalmailserver. But then i will be forwarded direct to my internalmailserver And never via my published proxy name. In fact, connection to internalmailserver is denied. Please can you also give me a hint how to change my config to use SSL? (how to create a ssl certificate) Thanks, Andrew
