After I installed Update Rollup 8 for Exchange Server 2010 Service Pack 2 (KB2903903) on my SBS 20011 server users on XP could no longer access the OWA web page. Every time they did they received the following error.
Users on Windows 7 had no problem. As you can see they are running IE 8 which is the lasted version for XP. Using another browser such as Firefox brings its own problems. The error went away as soon as I uninstalled the update. I did some searching on the web and looked through the notes on the update, didn’t find anything that helped. Anyone have any ideas. Thanks
