Thunderbird Tekoha Aty

I have this issue with my reminders for peoples' birthdays. I have an event on their birthday that comes from my Google contacts. That event has a reminder 1 week in advance. When the 1-week mark hits, I get an undismissable notification from Thunderbird. I can close the reminder window, but it'll show back up within a minute or two. I've tried removing and re-adding this calendar but it doesn't matter. When I look at the details for the event, I see that the Organizer field is Unknown Organizer <unknownorganizer@calendar.google.com>. My regular email address is listed as an attendee. This has been happening for at least the last several months, perhaps more than a year.

Hi there! After transferring Thunderbird from my old to my new computer, the calender does not show any appointment. Even it I set a new one this is not shown. But all appointments still exist because if I search for them the are shown in a list. Is there anyone who has an idea what went wrong? Thank you for any help! Norbert from Berlin

Whenever I create an event in the calendar, Thunderbird creates it in the "Task calendar" and I want it in my other, email named calendar. Can this behavior be changed? It's so frustrating because I have to edit the event and all the attendees get a second notice. Thank you

I got an email to attend a meeting. Thunderbird popped up a screen for me to pick where to store the event, Outlook, Google or iCal. I tried all 3 and did not get it added to Thunderbird calendar. Can this be automated?
