I have Exchange 2003 SP2 6.5 Build 7638 SP2. I am running IE 7 Version 7.0.5730.11 (128bit) Update Version 0 on my XP machine. I can access owa just fine. I have another XP machine with the same version of IE7 and all the latest updates from microsoft. and it can't load the page. i removed IE 7 on that one and tried IE6 (Which runs on a few machines and accesses OWA good) it wouldn't wortk either. I have about 6 machines or so in the building that are in this situation. I have set SSL2 and SSL3 in the browser and still nothing. Any ideas on why some machines can and some can't access https://mail.mydomain.com? Thanks
