If you observed, the ‘To-Do Bar’ in Outlook 2013 is turned off by default.



You can activate it by clicking on View-> To-Do Bar button in the Ribbon.


The reason why it is turned off by default is to dole out more horizontal space for clear viewing and because the individual To-Do Bar modules pop up every time you hover the mouse over the word Calendar People or Tasks at the bottom of the Outlook window.

It holds the option to display your contacts too.
