Use the Drawing toolbar (toolbar: A bar with buttons and options that you use to carry out commands. To display a toolbar, press ALT and then SHIFT+F10.) to add the shapes and drawings that you want.
If you are in Outlook, make sure you have a new message open.
Note When you drag a floating toolbar to the edge of the program window, it changes to a docked toolbar. Moving a docked toolbar may affect the location and size of other toolbars in the same row.
