Duplicated events in Calendar using Provider for Google Calendar
I'm getting duplicates of calendar items using the Provider for Google Calendar whenever I enter an event in Thunderbird. This doesn't happen when the events are posted elsewhere, on a Google Calendar. When I'm about to enter a new event, I can see a line labeled "Calendar" that gives me 3 choices ... 2 of them are the same, like xxxxx@gmail.com and the other is GMAIL. I have 2 gmail accounts sharing on three devices ... my laptop, my phone and my wife's iPad. Once I've finished and closed the event, I wait a bit and I get the duplicated item beside it. When I right-click on an event that I've put into Thunderbird, I see a line that says "Organizer:" with my gmail address. I don't see anything like that when clicking on a duplicate that has popped up. There is also a Related Link ... https://calendar.google.com/calendar/u/0/event?eid=X2M5ajYyZTluNnRpajBiOWo2OWg2YWI5a2NkaGphYmIyYzhzNjRiOW02cGozaW9wcGNkaW04b2hnY2tfMjAyNDAxMTFUMTgzMDAwWiBnaGNoYXJ0ZXJzQG0 ... but it comes up as "requested URL not found on this server". I hope I've provided enough information here to get this situation resolved. Any help would be greatly appreciated. Thanks, Gil

I'm sorry I took so long to get back to you on this. I was having difficulty following your instructions since I'm unfamiliar with CalDAV. In the meantime, I came across the following using Copilot on Microsoft Edge. The second part of the suggestion worked out perfectly for me. Thanks. Gil.

I'm not sure I fully understand your setup. In any case, you don't need the Provider for Google Calendar add-on anymore for Thunderbird to connect to a Google Calendar. You can just create a new CalDAV type calendar on the network.
Press Alt or F10 to bring up the menu bar in case it is hidden. File (Alt-F) - New - Calendar Select 'On the Network' Enter your Gmail email address, and leave 'Location' blank Enter your credentials when prompted, and give permission for Thunderbird to access your Google Calendar.
Note, you'll have to allow cookies in Thunderbird for the OAuth2 authentication to work.
