Outlook 2010

 I use Outlook 2010.  My question is about the bottom of my received emails where the sender's name is to the left and the People boxes are to the right.

Below the sender's name is ALL

                                             WHAT'S NEW

                                             MAIL

                                             ATTACHMENTS

                                             MEETINGS

No matter which one I click on, the reply states THERE ARE NO ITEMS TO SHOW IN THIS VIEW even though there are items.

Items were displayed in the past and then one day they weren't and I'm not aware of anything I inadvertently changed.

How do I fix the display?

Thanks
