You can also add a Google Calendar to Zimbra via the command line using the zmmailbox command. Run this command as user zimbra:

zmmailbox -z -m user@your-zimbra-domain.com cf --view appointment --url "https://calendar.google.com/calendar/ical/user%40gmail.com/private-djheouih783lsei73wehke84j/basic.ics" /Google

 

Add Google Calendar via WebDAV

In case you also need to be able to edit your Google Calendar from within Zimbra, you can do this via the steps described in below link. This option does require a paid Google subscription.

Gotchas

The Google Calendar shared via iCAL is read-only. You can display the Google Calendar in Zimbra, but you will not be able to edit/add appointments. This is useful for viewing appointments, events and availability.

Thanks,
Your Zimbra Team
