Hi, Why can't I see or find the calendar in Thunderbird anymore? Is it no longer appearing next to "New Message" like it always did? I have a lot of recurring events on it from the many years I've been using it, and I need to add more events. Please advise. Thanks

Just moved to a new computer and am having trouble importing my previuos TBird calendar. From my prior computer backup (created with Macrium Reflect) I have tried moving the local.sqlite backup file to the calendar-data folder in my new TBird profile. However none of my prior calendar events have loaded into my new calendar. Is there another process or file/files I should be using? Thanks in advance. Rob W.

When I go to set a custom time for when an event's reminder will happen, it doesn't matter what date or time I put, when I click OK, it sets the date to be today, and the time to the next hour, if I use the date and time picker dropdown thing (clicking the arrow instead of typing it in), the date does set correctly, but the time is impossible to set even like that

I have been using Mozilla Thunderbird for many years on Windows desktop (now Win 11 ver 24H2 for x64 based systems).

In the last week or two Thunderbird has been giving me unwanted reminders for future events on my Google Calendar. (They are Thunderbird reminders, since they disappear when closing Thunderbird). If I try to dismiss them I get an Error Code: Modification failed. Status Code: 2,147,500,037, null Server Replied with 400

Dr google suggestions to get rid of them only apply to iOS or Android, nothing mentions windows. The problem does not occur on my iPhone.

If I just close the reminder windows they reappear in a few minutes.

I uninstalled and reloaded to be sure I had the latest Thunderbird.
