Before using the Access ACS built-in calendar, you must set up your calendar types.
With calendar types, you can establish which users have certain controls to your organization calendars. Once you set up your calendar types, you can assign them to user profiles or individual users.
Members, attendees, and group leaders can only access calendar types to which they have rights. Users with View Only rights to a calendar type can view events only. Users with Full Rights to a calendar type can view, add, edit, or delete events.
You can also assign colors to your calendar types. If you assign a color to a calendar type, events associated with the calendar type display in the selected color.
