If you have less number of appointments or meeting scheduled in your Outlook, then you can change Outlook 2013 and Outlook 2010 settings to display only the active appointments. This can be done by changing the default Calendar view setting.
From Outlook 2010 Calendar screen, click the View menu
Then click the drop down arrow available below the Change View menu option. From the Change View drop down list, select Active menu option. This would change Calendar display to list only the active appointments.
