Copy Toolbar Menu
When you copy a built-in menu (either from an available menu bar or from the Built-In Menus category), Access does not make an independent copy of the original. So, if you copy a menu and then change some of its properties (for example, you delete one of the commands from the menu), you’re also affecting the built-in menu. This is why you must use the New Menu command for the first menu level (File, Edit, View, etc.) on a custom menu bar. If you were to copy the originals and delete unwanted commands from the copies, you’d be deleting them from the built-in menus as well.
