The ToDo Bar is the “headquarters” of your Outlook account’s task management system. It consists of four basic parts: the Date Navigator, the Appointments section, the Task Input Panel and the task list itself. Although the maximized ToDo Bar can’t expand any further, you can manipulate the size or display of any of these. For instance, you can turn off the Date Navigator or reduce the number of appointments displayed in the Appointments section—which allows between 0 and 25 appointments—to free up more space for displayed tasks in the task list.
To minimize the ToDo Bar completely, drop down the “View” menu and click “Minimized” under ToDo Bar. The keyboard shortcut to minimize the ToDo Bar is Alt + F12. This makes it easy to manipulate your ToDo Bar without time-consuming clicks and drags.
