I cannot delete this appointment reminder that was sent to me from Joe Cooper Ford when making a service appointment. Keeps popping up, over and over. I cannot edit, delete, change, there is no "read only" option as recommended below. This appointment does not show on the calendar either so I cannot right click as also recommended below. This is very annoying.

Status Code: 2,147,500,037, null

Server Replied with 400 If you're seeing this message after snoozing or dismissing a reminder and this is for a calendar you do not want to add or edit events for, you can mark this calendar as read-only to avoid such experience in future. To do so, get to the calendar properties by right-clicking on this calendar in the list in the calendar or task view.

In Thunderbird 143.0.1 (64-bit), my appointment invitations are no longer sent automatically to the respective email recipients, as they used to be. I can't find any settings where I can change this. Under ‘Troubleshooting Information’ in the line ‘Send appointment notifications via email’, the value is not set to ‘true’. I look forward to your help. Best regards, Thorsten

I have used Thunderbird to manage my google calendar on PC, windows 11, for years. It seems now that when I add an event, hit save and close, it is not saved. All the events show. I can add events on my phone, and they show up in the calendar on Thunderbird, instantly. I just can no longer add events. I can try, but when I save, they do not appear in the Thunderbird calendar, or in Google. I did just recently change my password in Google, and had to re-authenticate Thunderbird, I suspect that's the instigator of the issue. I just feel I'm missing something. One note-if I click on "add account", there is no option for calendar anymore. Maybe this is gone.
