The only workaround is to set you calendar read-only in thunderbird and use the web interface to create events. I have been waiting for months for this fix.

This is aweful.

Thanks for the hint @roccopietrini

Apologies this has been an issue so long  💔 This is on my radar, fixing this with 91.0.2

@kewisch 91.2.0 here
I create a google calendar event with attendees.
I open it in thunderbird and I can see and edit everyone.
But if I save it in thunderbird, all attendees are removed.

@kewisch 91.2.0 here I create a google calendar event with attendees. I open it in thunderbird and I can see and edit everyone. But if I save it in thunderbird, all attendees are removed.

Same experience for me.
EDIT: I did notice the following error in the console after hitting 'Send and close' on the event (after adding Attendees), not sure if related? #149

This is still happening to me in version 102.0.0. When I come to the time of the event everyone in my meeting reports that they did have the event in their calendar but its now disappeared, this is because the event loses all invited guests and to my knowledge I am not modifying the event from thunderbird.

Same, for security reasons I have calendars in TB only in read-only mode. This is a huge drawback and a big reputation loss for TB calendars overall.

Still seeing this behavior in 102.0.3. When I dismiss the notification for an event, it actually modifies the event and removes all invited attendees.

Still existing in 115.0.2
Accepting/editing an event created on Google Agenda or dismissing reminder WILL REMOVE ATTENDEES!!! They'll receive a "Cancel" notification.

Still seeing this as well as of yesterday with 115.0.2.

Same here on 115.0.2

I am also experiencing this problem. Very frustrating. Any news on when this will be fixed?
