Problem here, story below If I set up OWA to work with SSL, then even though I type https://etc etc it still says that the page must be loaded with SSL. If I remove SSL then I get proxy chain loop and I see multiple web sessions in ISA which I assume means packets going backwards and forwards. OK here is the story After months of trying I finally got OWA working. Then I tried to install a http virus scanning package on ISA. It needed IIS. So I temporarily enabled IIS on ISA. OWA stopped working. I removed the package and IIS. OWA still doesnt work.
