Google changed the Location URL of their CalDAV Calendars – Sept 16, 2013. Thankfully it is only a matter of changing the calendar address.
Google has decided to change the authentication mechanism for their CalDAV calendars to OAuth, which required some changes in Lightning to accommodate.
Due to these changes, the URL to access the calendar has also changed. The old endpoint will stop working after September 16th. This affects only Google calendars using CalDAV protocol.
Calendars using the Provider for Google Calendar or iCal read-only access won’t be affected.
– iCal read-write seem to be working on Sunbird/Windows
How do I know if I’m affected?
Open your calendar’s properties by right-clicking on calendar name and check if the location starts with https://www.google.com/calendar/dav/. If it does, you are using CalDAV and need to set up your calendar again with the new URL.
How do I set up the new calendar?
To use the new CalDAV Endpoint, you will need Lightning 2.6 and Thunderbird 24, which will be released tomorrow, September 17th. There will be a blog post on the release tomorrow, so please use the navigation to view the new post when its there to get the download links. Anyway, here are the steps:
– Download Thunderbird 24 and install Lightning 2.6
– Open the new calendar dialog (File → New → Calendar)
– Add a new remote calendar (On the Network → CalDAV)
– As a location enter the following, be sure to replace your email address: https://apidata.googleusercontent.com/caldav/v2/your-email-address/events
