Its now working! Rated 5 out of 5 stars

When you have instal a old version before and its not working or only 1 day do this (not mine solution!):

1. Uninstalled Provider & Lightning, shut down TB.
2. Removed the calendar-data folder
you find it here ( C:\Users\YOUR_USER_NAME\AppData\Roaming\Thunderbird\Profiles\uvvvzg0u.default)
3. Checked the folder for any Provider folders or files, if yes delete it
4. Edited prefs.js, and removed ALL references to calendar (there were numerous entries)
5. Re-started TB, and ensured everything was gone.
6. Reinstalled Lightning. Local Calendar was created
7. Rebooted TB, just to be sure.
8. Reinstalled Provider,
9 add your google mail account

Working again, and then not. Rated 1 out of 5 stars

Still the same problem as before despite following others comments. It works for a day then the next day things start to disappear. I have 5 calendars and after 1 day only 2 work now.

Works great! But: can't accept invitations anymore... Rated 4 out of 5 stars

Since I found lightning & the Provider for Google Calendar, I changed to the seamonkey suite for my daily business life. I am (nearly) completely satisfied!
But however - if I get Invitations, i can't accept them anymore. Additional it would be great, if any invitation could be transferred to one of my calendars - that I have to choose before. In the past all the invitations could be stored only in a "local" calendar, but I need them in my Google calendar. Export of the .ics-file and re-importing to a google calendar does work anyways, but sends additional invitations to all members of the event - so i can't use this workaround longer :-(

Working Again! Rated 4 out of 5 stars

I followed these steps (thanks, Dave Fletcher):

0. If you still have access to your local calendar(s), export its(their) ICS data.
1. Uninstalled Provider and Lightning, shut down TB.
2. Removed the calendar-data folder from my profile folder (one could rename the folder if a backup is desired)
3. Checked my profile folder for any Provider folders or files (I would have removed them if they had been present)
4. Edited prefs.js, and removed ALL references to calendar (there were numerous entries left behind by Provider)
5. Re-started TB, and ensured everything was gone.
6. Reinstalled Lightning. Local Calendar was created (no events).
7. Rebooted TB, just to be sure.
8. Reinstalled Provider, received the aforementioned 'version' error, but re-associated with all my onlin/Google calendars using network/Google option.
9. All events reappeared rather quickly as I reactivated (check-boxed) each calendar.
10. If applicable, import local calendar data you exported previously.

Rated 3 out of 5 stars

When this add on works... it works great! I love it to keep synced on my lightning calendar. the problem is that is does not work all the time. It seams to loose the connection form google calendar to lighting. It always seams to work from lighting to google. So if you are only using it to input information it is great. I do not blame the developer, I believe it is an issue that google created. In their infinite wisdom they keep fixing things that are not broken and do not tell anyone or give assistance to correct the problem. But with all that said I can only give this 3 stars at this time because it is not working 100%.

Tips for recent updates/installs Rated 5 out of 5 stars

I had the provider working erratically lately even though it was updated to the latest (suggested) version. The solution was, to remove the addon and the Google calendar as well. Then install it again (same version) and add the calendar again. After the reinstall the add calendar window changed as well (Google calendar + e-mail address instead of URL) and I got a list of all available calendars.

Additional tip: I couldn't find the list of (Google) calendars in either the calendar props or addon. Then I found that if I start a new 'add calendar' and choose Google Calendar again, I get the option to select the existing account and the available calendar list is shown again. It would be useful to add this info to the addon description.

Forget it Rated 1 out of 5 stars

Just randomly stops working. -Some- of my secondary calendars (not all...) sync and display but not the primary one? Sick of it, don't have time to troubleshoot and after spending an hour on line trying to search for an answer, realized that my time is far more important. UNINSTALLED

Works fine for me Rated 5 out of 5 stars

I wanted to clarify Arnoques comment. He wrote, that in order to turn on js and make the extension work correctly, you need to go to Preferences->Advanced->Config Editor and set "calendar.icaljs" to true (search for icaljs and double click on it).

If the extension is used in SeaMonkey, you must type "about:config" in the address bar, and press enter. Search for "calendar.icaljs" and double click on it. The value will change to "true".

The extension works fine for me on 2 windows computers. In addition, I'm using the same google calender on several android devices.
If the values are not shown at the first installation, retry the configure.

Thanks to Phillip for the good extension.

Best regards

1.0.3 IS WORKING FINE Rated 4 out of 5 stars

Thunderbird 31.3.0, Lightning 3.3.2, Provider 1.0.3, Windows 7 Pro

Working fine as of today, 12/31/14. On Dec 13 I submitted a review labeled HORRIBLE STILL. At that time I was highly frustrated. But I connected to the support forum and was able to find the cause of my problem, it seems like a few lines needed to be removed from my config file. I removed Provider and Lightning. Then I removed lines in config with "calendar.google.calPrefs", reinstalled Lightning and Provider. I was able to use the newer, friendlier, GUI to install 9 google calendars and they have been working like did for the past few years. Hopefully this info will help anyone else who is having problems with 1.0.3. But I think mine are history, and my Provider is great to have back again.

It works at the moment, with a config tweak Rated 4 out of 5 stars

This update works finally...I edited some sharing settings in my GMail settings and re-installed the add-ons. Now it works, I can add, update and delete appointments in multiple agenda's. Maybe, a better tutorial should be written :-)

WRONG DEFAULT STATUS - End Rated 4 out of 5 stars

(see my two previous comments)

Now I think I know what happened.

The day I switched to version 1.0.x (some day in November '14), the add-on suddenly turned ALL PRESENT AND FUTURE EVENTS to status "Tentative", leaving PAST EVENTS untouched.

But once this has been carried out, new events could be created normally, with the correct "Confirmed" status.

The only cure was lengthy manual reset...

I hope it won't happen again!

v1.0.3. still not working :( Rated 3 out of 5 stars

Unfortunately, update v1.0.3 doesn't seem to work any better than its precedents on my system (Win7 + Thunderbird 31.3.0 + Lightning 3.3.1)!

Nonetheless, i've not given up hope yet...

Edit: As suggested is tried unsuscribing and re-suscribing, but to no avail (other than getting my calendar to work for one single day)!

upgraded to 1.03 and look good for now Rated 4 out of 5 stars

Well after the extended problems with previous versions which were no fault of the developers i believe. This one has just synced and looks good. I hope it continues to work as it did previously as this is a very useful add on and i rely on it a lot.

KUDOS to the developer anyway for allowing us to use it, thanks.
