I installed this on recommendation to gain additional functionality in sync with Google Tasks.

What I did notice after a while was the Calendar was not updating existing entries when changed outside of Thunderbird. The synchronise calendar function seemed ineffective.

Only when Thunderbird was recycled, did it make an attempt to aligning its copy of the calendar with that which was shown on Google's server.

In the end, I disabled the plugin, which removed all the calendars, so I reinstalled Thunderbird to restore the calendars that were setup during that install.

It did get the Task functionality I sought, but the cost was too high, so I continued with my previous work-around.

Works well, but I might notuse it as extensively as most might with many changes to calendar items.
The reason for 4 stars is the reminder does not always allow me to dismiss appointments, not sure if its a Thunderbird / add-on issue. Its as easy as just closing the popup window though.

Why does this add-on require full access to my entire computer. That's a big nope (for ANYTHING requesting that level of access).

DO NOT INSTALL THIS ADDON! It is no longer needed to integrate Google calendars into Thunderbird, but it CAUSES MASSIVE PROBLEMS! I had to deal with crashes, ghosting, zombie meetings etc for a year before I noticed that all problems go away if I simply REMOVE THIS ADDON! I actually opened a bug in bugzilla and they told me, "not our problem, that problem is caused by the addon".

EN FRANÇAIS :
Bonjour tous,

Cela refonctionne chez moi, il faut suivre à la procédure ci-dessous :

Ce qui empêche ce "module" de fonctionner c'est un changement de l'API Google Calendar.
Pour refaire fonctionner ce module il faut :

1) Supprimer le module dans Thunderbird en exécutant Thunderbird en mode sans échec, faire la combinaison des touches "Windows"+"R", Il s'ouvre la fenêtre "Exécuter" et taper : « Thunderbird -safe-mode ».

2) Puis il faut supprimer dans Thunderbird tous vos agendas google créés avec ce module.

3) Puis il faut supprimer les autorisations données au module dans votre compte Google.
Une fois dans votre compte Google faite une recherche "applications tierces" et supprimer l'autorisation de "Provider for Google Calendar"

4)Réinstallez le module "Provider for Google Calendar" dans Thunderbird, ajoutez vos agendas google.
Une nouvelle autorisation va se créer vers la nouvelle API google Calendar.

Tout doit de nouveau fonctionner parfaitement, cela a été le cas pour moi.

IN UK, US :
Hello all,

It works again for me, you have to follow the procedure below:

What prevents this "module" from working is a change in the Google Calendar API.
To make this module work again you need:

1) Remove the module in Thunderbird by running Thunderbird in safe mode, press the key combination "Windows"+"R", The "Run" window opens and type: "Thunderbird -safe-mode".

2) Then you must delete in Thunderbird all your google calendars created with this module.

3) Then you must delete the authorizations given to the module in your Google account.
Once in your Google account, search for ”Apps allowed”and remove the authorization for "Provider for Google Calendar"

4)Reinstall the "Provider for Google Calendar" module in Thunderbird, add your google calendars.
A new authorization will be created for the new Google Calendar API.

Everything should work perfectly again, it did for me.

Calendar and Tasks:

It works, and I use it everyday. Many calendars!

But the syncing has to be improved when an appointment has changed on server and the laptop was in suspend mode with started thunderbird.

Many popup windows with the same question regarding where it has to be changed (on server or locally) and thunderbird has long response for everything.

Then it is terrible, the popup windows are too much and thunderbird has to be killed and restarted.

I have not found a setting to preselect this decision (not in thunderbird and not in the addon setting area)


Additional with google tasks (calendar: List of...user) it is only possible to set a day, but not a time.

Dismissing notifications is broken, clicking dismiss does nothing.

Changing events on GCal's web UI does not update the calendar in Thunderbird.

Seems to be fundamentally broken. It *gets* information from GC, but any *change* to a GC entry causes [at least] two problems:

1) the local (to Thunderbird) calendar entry is not updated
2) you get into an inescapable UI loop with two dialog boxes, one of which says the item has changed and asks whether you want to discard/submit.

Regardless of the selection, you then get an event reminder popup, which when dismissed results in the first dialog box appearing, again. And again.

Nice idea, but just doesn't work at all.

Works great! Developer was fast-acting when Google changed their OAuth API and broke everything.

thunderbird version 102.7.1 (64-bit). Does not sync with google calendar and even does not display Google Calendar as a possible choice when setting a new event. 5 stars if this problem is fixed and if it is given to the user the possibility to choose the default calendar.

2 months ago,it would have a 5* rating. Now it's stopped syncing and I have missed appointments, so I must give it the lowest rating. According to other reviews, this is a problem for many that has not been addressed.

Please fix it ASAP

Great application. I will be the first to install it.
Unluckily, there is a bug for unknown reasons for some users, not only me. When I close a calendar schedule notification, I get a popup saying that there is a change in the data on the server, and when I close it, the calendar schedule notification occurs again. This loops endlessly...

Since I updated to TB 102, the Provider for Google Calendar has not been syncing when Thunderbird is open. I found that it syncs when I start Thunderbird. I have found a workaround that will cause a sync to happen while Thunderbird is open. I go to the Add-ons section and select Provider for Google Calendar. I disable the add-on then enable the add-on. After I enable the add-on a sync with Google Calendar occurs and all events are displayed in the Thunderbird calendar.

This has been an excellent 5 star add-on for many years but since TB 102 on our PCs, it only syncs with Google Calendar when TB is started. After that, there is no sync at all (even if manually requested). :(

Apologies in advance for the low rating but apart from this and a couple of other small niggles, the add-on has been great for many years till now. BUT Since Thunderbird updated to 102.x it is taking 5 minutes to start with intermittent slowdowns. Very frustrating. I have Disabled provider for google calendar and everything works fast again, except no google calendar visibility of course. Please fix this. I made no changes my end, just took the automatic updates when they were offered! I read something about all calendar events being re-read or something like that. Problem seems to be since that feature or bug was introduced.

Windows 10, TB 102: syncing tasks does not work without restarting TB, unfortunately, just as other users reported. Otherwise very good add-on and essential for my workflow.

Used it on MacOS Monterey 12,5.
Unfortunately, it appears to have a memory leak - after 24-48 hours, Thunderbird went from 1.5 Gbytes to 30 G :-(
And, quite often, there was a thread eating up 100% CPU time on a core, making Thunderbird slow and not very responsive. Uninstalled the add-on - and, voila, now my Thunderbird is 1,2 Gbytee pretty stable for many days, and quite responsive. And the calendar stuff works withou Provider - and I do not need the task stuff.
