Vista breaks when using Exchange 2003 OWA
Ok, you installed Vista on a user’s PC and then they try access their mail via Outlook Web Access (OWA). Umm… stuff is broken.
If you are running Exchange 2003 here is the hotfix. Yes hotfix, a scary word in MS lingo. It is an ActiveX update for the server. I’ve installed it several times without incident so you shouldn’t have any problems. If you do, uninstall the hotfix, reboot server, call Microsoft.
You’d think this would be vetted by Redmond and released via the normal patch cycle but that seems to be an afterthought for an OS that was 5 years in the making.
