Hello. I installed the rpc over http proxy service, i then enabled Outlook Anywhere with external hostname: exchange.domain.dk, however it dosen't seem to work, since i can't connect with rpc over https. I have an UCC certificate installed for exchange.domain.dk and other names. When entering https://exchange.domain.dk/rps i get prompted for login/pass when entering i get a blank page.If i push cancel i get this error message "You do not have permission to view this directory or page." Tried both with and without mark in "allow ssl offloading". And basic authentication is marked. (also in outlook) OWA works fine. I can connect to https://exchange.domain.dk/owano problem. Could bea simple outlook configuration mistake, but i have followed several guides, and no luck, so i kinda doubt it. Guess i am missing something else? Server 2008 Exchange 2007 SP1 Outlook 2007 Thank you for your reply. /Michael
