I have installed Windows 8 recently and I created a Live account. Before joining to my domain, all apps in Metro UI works fine (Mail, Calendar, People, SkyDrive, ...).
After joining to domain, they are not working.
When I log in with my local user, the apps are working. But with my domain account login, they are not working (when I click them, nothing happens and the apps do not run).
Edited: it seems that it is an issue and there are many people with the same problem.
