In addition, when you are working within a view, the Navigation Pane displays the folders within that view. When you select a folder in the Navigation Pane, that folder becomes the active folder and you can work with the items within it. For example, in Mail, select the Inbox folder to see new email messages.
The Outlook-style Navigation Pane is similar in functionality to the Outlook 2010 and 2007 navigation bars. It is the ideal choice for building Office style user interfaces.
