In addition to the default Microsoft Office Outlook Calendar, you can create other Outlook calendars. For example, you can create a calendar for your personal appointments.
The new calendar appears in the Calendar Navigation Pane (Navigation Pane: The
column on the left side of the Outlook window that includes panes such as Shortcuts
or Mail and the shortcuts or folders within each pane. Click a folder to show
the items in the folder.).
To view a calendar, select the check box for the calendar name. When multiple
check boxes are selected, the calendars appear in side-by-side view.
Tip To delete a calendar, right-click the calendar name in the Navigation Pane, and then click Delete calendar name.
