It is a nice add-on that helps me to synchronize several google calendars to thunderbird.
There is only one (quite big) problem: it stops synchronizing the newest events when a calendar consists of more than 2000 entries.

This review is for a previous version of the add-on (2.7).

I had the same problem as the last couple of reviewers, the upgrade to Thunderbird 45 caused all of my Google calendars to no longer connect at all. After a little investigation I noticed that this plugin has not been automatically updating, it was still on version 1.0.2 I think. So after manually updating this plugin to version 2.7 and restarting Thunderbird, all my Google calendars are back and everything works properly. Hopefully this will help someone else with the same issue.

Once I realised that appointments were being set in the "Home" calendar by default, and that this was not what I needed, it all worked smoothly.

When setting an appointment, in the event dialogue there is a "Calendar" drop-down where you choose the calendar in which you want the event to be recorded. I was not paying attention to this; it was set by default to Home, and was therefore not being sent to my Google calendar. This caused me some frustration as I initially thought there was a fault with the synchronisation because the events were not appearing in Google but I then realised there was nothing to sync as I was actually setting them on the local Lightning "Home" calendar only.

For my purposes, I have deleted the "Home" calendar altogether so now all events will at least be recorded in one of my Google calendars if I forget to select one. This works fine for me and I now have an integrated calendar in which I can view and manage my personal as well as my business appointments.

Excellent Add-on. Makes Lightning work with Google Calendar.

There seems to be a limitation when setting the Sync Refresh Rate. It cannot be set any faster than once every 30 minutes.

I don't think this is a limitation of Lightning. Seems like it may be a limitation of what the Provider will permit.

Is that correct? Is there some way to customize this?

Many thanks

Unfortunately this is hard to change. The limitation is in place so I don't hit the API call limit. I have already reduced the number of requests as far as possible, but there are a lot of users and they make a lot of requests :)

Great plug-in, very useful.
I do struggle with what seems to be a bug though: Frequently I get a modal window complaining "This item has recently been changed on the server. Submitting your changes will overwrite the changes made on the server". I am offered to submit or discard my changes, but regardless of my choice the error persists. Is anybody else experiencing this?

Works great with google calendar BUT repeating events created in Thunderbird do not sync to google. Repeating events created in google sync perfectly back to Thunderbird. Any explanation?

This add on is a really useful tool. I made a contribution to support it.

Minor complaints:

Under "Create New Calendar -> On the Network -> Google Calendar -> Locate your calendar", it says "Please pick an existing session or enter your email address to create a new session". Most people won't be able to figure out what a "session" means here. Basically, it means enter the email associated with the new Google calendar you're setting up (strictly speaking, you're setting up a new Thunderbird calendar connection to your existing Google Calendar, but whatever)

Hi Ben, thank you very much for the contribution and the suggestion. I agree it would be good to get this technical term out of the extension and it is easy to describe differently. It may take a bit though, because the extensions is translated into many languages.

It works perfectly reading and writing to my Google calendars. With Lightning it's the best calendar app around.
- great you can scroll down smoothly, not just a month at a time, which is only partly implemented in Apple's calendar and not at all in others
- you can see the time on the event, again can't on many others
- can print out a month's events

Thank you! keep it up

The guide is a tiny bit outdated I guess, because a couple of the final steps were different. But it was not hard to guess the right selection. All in all very straightforward. It took me about 5min. to adjust the settings. Thank you!

After over a year the add-on still slows down Thunderbird to almost stand still.
After each update it requires to authenticate each calendar again. Which is quite annoying.

This review is for a previous version of the add-on (2.7).  This user has a previous review of this add-on.

Unfortunately I can't fix the reauthentication on update due to the way Google OAuth tokens work. If I were to keep the same token across versions, I would have to disable a broader range of versions in case major issues occur, making more users unhappy. I already try to keep this down to a minimum though.

Regarding the slowdown, this should only happen on a full synchronization, the first time the calendar is downloaded. I am happy to help debug this further in case you contact the support email.

I had high hopes, but after installing this, half my meetings were changed as follows:

* moved forward in time by an hour;
* calendar-default visibility settings were replaced with "public";
* repeating calendar entries were reconfigured as a series of exceptions.

This review is for a previous version of the add-on (1.0.4). 

I'd appreciate if you could contact support on this issue. The time moved forward should be a display issue fixed in 2.7, the repeating entries thing only happens if you make changes to occurrences and is related to Lightning, and the visibility thing sounds strange to me.

Works fine! One of the best calendar add-ons because win 10 calendar does not (yet?) show past events, in the android world it is, as far as I know, only Calengoo which presents all (!) events from the Google calendar.
Downloaded Thunderbird, Lightning and thirdly this "Provider for Google Calendar".
I'm not thee expert in all these things, just followed the instructions here:
https://support.mozilla.org/de/kb/mit-lightning-auf-google-kalender-zugreifen

Result: Thunderbird loads fairly quickly, only the first search-through took 30 sec with five years of events (average one entry a day). The whole thing took me five minutes.

Thanks for this module
You wrote on October 5, 2015 ("Wrong" - response to "unusable with large numbers of events"
I have the same problem : the sync of 1000 events does the sync of events in my agenda from 2007 to 2011. But nothing after 2011, the 1000 first events are in TB but not the current ones.

You said "There is an advanced option to change the batch size" : how is it possible to use it ? I would set 3000 then.

You said also "Once the initial synchronization is done, the synchronization token is saved locally and all future synchronizations are incremental: only changed events are downloaded. So, let me guess, this is exactly how synchronization software should work? Yes, I thought so."

Then as you guess "the case is probably that the initial sync is not complete, hence the token is not saved on shutdown and next time you start up, it attempts to start over. Please give it some time." How can I know if the initial sync is complete or not ? In the bottom bar, there is written "synchroniszation finished at 19:18:14, but my last event is june 20th, 2011.

Thanks a lot

This add-on makes the calender extremely slow to load and to browse through.

Update: unsubscribing birthday calendar helped tremendously. I've updated my rating to 4/5 stars. It would have been 5/5 if it wasn't for such an work-around.

I'm all of the sudden experiencing severe slowdowns in TB. I've been using this add-on for quiet some time and have been happy with it, but since yesterday, TB now needs up to 2 minutes or so, because I can actually use it. While in TB and writing a mail, I occasionally experience slowdowns here as well. Could be syncing related.

I've tried disabling all calendars, but that didn't help anything. Only by disabling this add-on I can access TB normally.

This review is for the newest versions at the time:
Thunderbird 38.3.0
Lightning 4.0.3.1
Provider for google calendar 1.0.4
The setup was very straightforward. (you have to have the Provider addon installed and enabled)
File->New->Calendar->Network Calendar->Enter gmail address->Enter gmail password->Choose Calendars to sync

That was it, you are ready to go.
Avoid older instructions in thunderbird support using xml instructions and such, it is not needed.

Philipp thanks for your work on this Add-On, it makes checking my family google calendar very convenient. One comment on the sync issue which I think has been brought up in other reviews: Mine does a full sync of 756 events each time I start TB. Basically I wait until that sync is complete (about a minute), then TB works just fine. Question - you mentioned that a "token" gets saved on your PC after each full sync so it knows to sync only incremental changes. I have let the entire sync operation complete. How do I know if this token has been saved? Or is there some other configuration option I'm missing (perhaps saving cookies?) Thanks again.

I have been using the extension for a while. I really need it but I have issues related to syncing too. It happens very frequently and freezes Thunderbird for a while. I have to say that I'm using many calendars at the same time, and that I use to delay many alerts. As I see that syncing is a complicated issue, I 'm thinking about a workaround: having a button that turns syncing on/off on demand! It would be wonderful!
Thanks for the extension.
