How to add iCal Calendar

New Contributor II

Currently I'm attempting to add a Office 365 account calendar to everyone's machine. This account would be strictly for a calendar. How do i add iCal Calendars to a machine? Cant seem to find it under configuration profile and managed preferences does do anything when i do it that way. Also how do i add an exchange calendar? I assume i use the IMAP server ports as the server address but wasn't sure if there is an easier way.
