#1 The ribbon
Microsoft first introduced the ribbon in Office 2007. However, it was absent from Outlook until now.
If you look just above the ribbon bar, you'll notice a small icon you can click on to send and receive messages. The area where this icon appears is known as the Quick Bar. Icons in this bar are always available regardless of which task ribbon you've selected. By default, only the Send/Receive and the Undo options are shown. If you click the down arrow next to the Send/Receive icon, you can add more icons to the Quick Bar.
