I read about problems with Outlook connector not working on windows 8. I have that problem too.
One additional problem is the advanced version of the web client on windows 8 machine also hangs at the loading screen. If I switch to standard or mobile then it loads as normal. Anyone else see this problem? Does anyone know, is there a bug already filed? Any possible fix I can look at implementing (I have a bunch of new computers I would like to install)?
