Hello there... I am having an issue with and not really sure what is wrong. I've set up an ISA server for an OWA solution. I have gone over my ISA configurations over, and over, and over and can't seem to find any mistakes. It seems that everything is working but when OWA loads it doesn't load all the way. It loads the everything, which is very slow, but then will not load any of the boxes (inbox, sent, calenders, etc.). I've tried accessing it internally and externally but the same issue both ways. I've looked at the firewall rules we have and everything is the same as it is at my other sites. I am using PKI certificates and a the users CAC (Common Access Card) to login to OWA. When it loads the initial page it asks for the certificate, then the pin. Then it brings me to the web certificate error page, asking if I want to continue or close the page. One I select continue it prompts me for my certificate again. Has anyone experienced anything like this? I have had other engineers look at this and they can't seem to find anything wrong either. Can someone please help?
