The People Pane in Outlook appears at the bottom of each email that you open. I found it quite annoying since it uses up so much space, but I wasn’t sure how to remove it. I found myself closing it manually on every email in order to see more of the message. To remove it once and for all, do the following.
In Outlook, Click the View tab, then Click the People Pane button. From the People Pane menu, Click the Off option.
