My Calendar:
You can sync your own calendar to Google. Changes in one end will be reflected in the other. For instructions, please click here.
Firm Calendar:
The Primary Subscriber can sync the firm calendar. Once the calendar is synced, Administrators can make changes to firm appointments where the firm is the creator of an appointment (not attendee). Otherwise, if other firm members wish to see this calendar they would need to use a feed (a one way push from Clio to Google) or you can share the firm calendar on the Google side.
Other User's Calendars:
You may want to see the calendar of other firm members in Google. You can not sync this between Clio and Google, but you can either set up a feed or share on the Google side.
Other "New" Calendars that you Create:
If you create a Calendar in Clio, then only you are able to sync it to Google. Otherwise, if other firm members wish to see this calendar they would need to use a feed (a one way push from Clio to Google) or you can share the calendar on the Google side.
