You can synchronize any calendars that you own or any calendars that you can subscribe to. The calendars you are subscribed to are in the MyCalendars Panel. The calendars you have permissions to subscribe to can be found by selecting the "View Calendars in the System" icon on the MyCalendars Panel.



If you do not have the appropriate permissios on a calendar and you synchronize that calendar with your device, you will not be able to change the events on that calendar because you do not have permissions.
