Outlook Calendar displays no events scheduled

Events in calendar all of sudden disappeared.. It has been working just fine until 2 days ago. 

I sent out a few meeting requests and received response from people I invited but the meeting/event is not in my calendar.

When I open "my day" under tool, i could see my meetings.. 

Can anyone help?
