Hi Claud -
I cannot get OWA to work with IE10, which is my preferred browser - despite the changes to the ActiveX controls suggested by the community. However, it works fine on Chrome. I don't see any other option at this point.
I am using a Windows 8 Pro Lenovo Tablet 2 and a desk top version of IE10.
OWA works fine on my PC with Windows 7 and IE9.
