Only thing I did after that was go into each added calendar's properties and checked the appropriate e-mail address for invitation management (or None if not using invitations). rather than the googleapi:// URI that this extension used. The calendar address once this is done is.

I'm then presented with the full list of my Google calendars (including calendars others have shared). I then get prompted to log in to Google and authorize Thunderbird to access my calendars. If you add a Google account afresh, it will automatically discover Google calendars and contacts and import them.Īs I upgraded, I had the same issue that my existing calendars were not working, but I removed those calendars and re-added as follows:Īdd calendar, choose "On the network", enter Google e-mail address for "User name", enter " " in "Location".

It also works natively with Google contacts now! There are some mentions in the release notes of "Calendar: Remote calendar auto-detection now supported" but no specific mention of Google. Thunderbird 91.0 seems to support read/write access to Google Calendar natively (but also not working with Tasks) - I have now uninstalled this add-on and everything is working (so far, very well).
