Quick installation guide to setup your Google Calendar in Thunderbird 31.2 with the Lightning Calendar Addon 3.3.1. You don’t even need to install the ‘Provider for Google Calendar’:
- Create a new calendar by right clicking on the calendar pane, then select ‘On the Network’
- Select ‘CalDav’ as you remote calendar format and put the following url as the location: https://www.google.com/calendar/dav/calId/events and replace calId with your calendar id. You can find it in your calender settings after logon to calendar.google.com. It’s usually your email address.
Note: use /events and not /user in the url, otherwise it won’t work
