The Calendar Overlay function is a convenient way of looking at all the events in one place instead of accessing your personal calendar or the group calendars separately in order to create a list of all the events. It is also a very helpful feature to use when organizing meetings or functions with other members on your team.
You can overlay your personal and/or the group(s) calendar in one view using the Calendar Overlay function. Selecting this option will enable you to look at all the events scheduled for the calendar view that is currently active by the month, week, or day.
To overlay your group and personal calendar, you must do so from your personal calendar. For additional information, refer to the Calendar Overlay topic in the Personal Calendar section in this help file.
