Dear Exchange list, I have a working setup with ISA on one server and Exchange on another. Only the ISA server has a public IP address. OWA is working via SSL on the IIS services on the Exchange box, with HTTPS requests being directed to it by ISA. This was setup by myself and has worked well for a year. We have just had a consultant suggest that it would be much better if the ISA box did the IIS work for OWA, ie:- that the IIS services on the ISA box dished up the pages for OWA. Is this possible? It would mean starting the IIS services on the ISA box for a start, and I don't think it would be able to use the default ports. What are you feelings about this? I don't like to change a working setup but want the advice of the experts. many thanks Andy Fairley Opera North Leeds UK
