The Outlook Calendar lets you view any number of consecutive days by simply dragging across the days in the Date Navigator (the small calendar that shows the current month). For example, if you wanted to check your schedule for the first two weeks in December, you would switch the Date Navigator to December and drag across the first two weeks.
But suppose you need to check your schedule for every Friday in December? It’s easy, if you hold down the CTRL key while you select the individual dates in the Date Navigator. Outlook will display your schedule for only the selected dates in the main window. To remove a date, keep the CTRL key held down, and click it again.
