I got a strange issue in Outlook Web App 2010, im not able to access Settings -> Mail on some clients.
When i click on Settings and afterwards Mail, it says Loading and the loading disappears and it returns a blank (White) screen.
See attached image.
I got an Exchange 2010 SP2 with RU3 installed.
I tried on different client machines, and it works great on some machines with IE9 installed, and Works perfectly in IE8 - but if i upgrade IE8 to IE9 the problem occures.
I tried to perform a reset on IE, clear browsing history, and so on - but that did not help.
