In the Calendar folder, you can schedule appointments and review your tasks. An appointment is a scheduled activity that does not involve anyone else. A task is an activity you must perform and track to completion. To manage your time effectively, you must be able to move easily from one date to another within your Outlook Calendar and to display each date in the desired view. The Calendar toolbar offers quick access to various Calendar views. The Date Navigator, which looks like a monthly calendar, helps you speedily move from one week or month to another. You can even show two.
