It works with Thunderbird 128.0.1esr, but it took me a while to find the button.

To access it, go to the email tab, and you'll see the Google Calendar icon in the upper right corner of the window.

I plan to use this extension because my company uses Google Workspace, and when I add the calendar in Thunderbird, it only shows the free/busy status due to company policy. There might be a way to add the corporate calendar natively in Thunderbird (my Alexa can see my calendar, so why can't Thunderbird?), but I haven't found a solution yet.

Overall a good idea and I'd love to use it. Unfortunately, the field for adding a description of the created event is inactive. For this reason, it is useless to me, and for that, I uninstalled it.

No longer able to update Google Calendar from this plugin, unfortunate as is has been working fine for years. :(

This add-on was working wonderfully until I updated Thunderbird (78.6.0 _ 64-bit) and I can no longer sync my calendar.

Perfect. That's what I needed. Google Calendar within Thunderbird.

Honestly, just installed BUT -- button works perfectly, display is very nice -- updates ARE BI-DIRECTONAL. This is what I looked for a few years ago and never found.

Uso mais de uma conta Google, e agora quero que a extensão trabalhe com a minha outra conta Google, mas ela não está permitindo fazer a mudança. Teria como resolver?

Very useful, no synchronization and problems, just Google Calendar.

OMG THE BEST GOOLGE CALENDAR PLUGIN.

I bought a new laptop and had to install a new version of Thunderbird 68.8.0 (32-bit). Unfortunately, the old Google Calendar extension by Philipp Kewisch was not compatible with the new version.

Then I discover this Google Calendar Plugin by
I didn't have to uninstall the old Thunderbird email in order to use the other Google Calendar extensions that were offered by other developers.

This plugin works perfectly! Thank you! I saved a ton of precious time not having to sort through the forum to find a work around.

Excellent; the ONLY Google Calendar addon that works with TB 68+
Google Provider and others stopped working.
Notice it puts a small button on bar which you need to press to get the calendar.
