I just noticed recently that my chat functionality on the right bar of outlook.com is not working anymore which used to be worked fine before.

When I click on my :-) button and it just keep signing in and never end.

I tried my IE10 the latest windows update and the latest Firefox, all are the same behaviour.

My Skype can signed in without any problem on both Windows 8 App or on Windows Skype client.

So i'm wondering this may just the issue of my outlook.com website, anymore can help me would be much appreciated.
