Is there any way to select other than the "home" calendar as standard? Have tried to change order in the calendar setting, but when I accept a meeting invitation it always place the meeting in the home calendar. I would like to select the syncronized Google calendar.

The syncronization with Google calender works perfect when manual enter something.

I added a CalDav calendar to Thunderbird that is hosted on a Nextcloud instance. While the calendar view looks decent, the tasks view is completely bloated with old, already completed tasks, some even from 2023. I selected "open tasks" or "current tasks" (? German translation) from the menu on the left side. It's not that all of the tasks are misclassified: When I go to completed tasks, there are hundreds of (correctly) completed tasks listed, but still.

Furthermore, the sub tasks of a main task are not grouped. Is this a known limitation or am I missing some configuration?

In general, as of now, the task view is pretty unusable for me. Anything that I can do to help debugging this?

Dear all, I have a couple of calendars on the disk as network calendars (file:///...ics) with offline support, and I just realized that I cannot delete any event. These calendars are not read-only, I can see the option delete, both with right-click on the event and double-click to edit the event, but after pressing delete, the event remains on the calendar. Just pressing the delete button on the keyboard after selecting the event has the same behaviour. If I try shift the events from one calendar to the other, they do appear in the new calendar, but they do not disappear from the old. I have restarted Thunderbird, and also tried this on another computer with the same results. Both szstems are Windows 11, Th underbird 115.10.1 I would be very grateful for any suggestions

Dear all, is there an option to have Thunderbird sync network calendars once upon start? I have a couple of large network calendars and repetitive syncing causes performance problems, but on the other hand, if I set sync to Manual, Thurderbird does not sync upon start and shows only the events that had been cached locally (off-line) in the past, but not any events meanwhile added to the network calendar by other clients. Thus, I either have to remember to manually sync once every calendar after each program start, or I have to activet syncing every xx minutes, which causes the programm to periodically freeze for some time (during syncing). Is there any good solution to this? Is there maybe an option in the config editor "sync upon start"? Thank you very much.

Thunderbird is is displaying 24hr in emails and calendar but the system is set not to used 24hr I'm running Linux Mint 19.3 (64-bit) Thunderbird 102.11.0 (64-bit).

I'm having a really annoying problem where Calendar events, even tho they have reminders/notifications properly set up, just don't actually trigger these notifications when they're supposed to.

Are there any logs or debug settings or anything I can do to troubleshoot this further? All of the direct UI settings are definitely set up correctly. And there are other events for which notifications work fine, so it's not that notifications are broken altogether

Will there ever be an option in the calendar to schedule links to video conferencing platforms like zoom or teams or google meet?

Lot's of other 'smart' calendars have this as an option. For example, when I use google calendar on a browser there is a zoom plugin so when I schedule an appointment it automatically generates a meeting invite for the attendees and put the meeting on my zoom app.

I know that this is probably reliant more on the companies [Google, Microsoft, Zoom] to make an extension for this, but it would be great if this could be implemented in the future.

Hi folks, I am wondering if there is a way to change the behavior of the pop-up reminder window in Calendar. When I have missed reminders (e.g. a task set for today at 8am and it is now 9am), the task is visible in the reminder window that pops up every time a reminder is active. This is fine. But if there is a past reminder (not resolved), every time I add a new task (or edit a past task) to the calendar, the pop-up reminder window opens and comes to the front. Let me describe the example: I missed (knowingly) a reminder at 8AM. Now, at 9 AM I need to add 3 new tasks to the Calendar. After setting (or copying, editing) each new task, the pop-up reminder window is focused on the front. Can I change this behavior so that the reminder window only pop up when the reminder is due and not in the case a new task is set up or old one edited?

Hello! I am facing the issue with time zone translations. Here is what I do. First, I create event on web-interface of the google calendar. That account is linked to TB's calendar. This calendar has settings for my timezone as in the first screenshot, that is GMT+3 for Kyiv, Ukraine. It is actually GMT+2 + daylight saving hour in effect. Country is also set to Ukraine. Next, my Windows 11 system is set to set time and timezone automatically, region - Ukraine. It displays UTC+2 Helsinki, Kyiv,... I guess it's Windows settings display quirk, because time is correct and WSL console shows

~$ date -R Thu, 18 Apr 2024 18:59:25 +0300

My TB's calendar is set to have system's timezone as in 3rd screenshot.

Now if I see my event in TB calendar, it is placed one hour later, say 9 am event starts at 10. So reminders also come hour later. Also strange thing is that event properties in TB show correct time like 9:00 till 10:40, but for some strange timezone Europe/Zaporozhye, as in 4th picture.

However, if I set TB's calendar manually to Europe/Kiev (which should be Kyiv, but that's another story), then events are shifted hour up to their right place, 9 am. So this is my issue: when I set calendar forcibly to Kyiv timezone, it does translate it right. When I ask calendar to rely on system's timezone, which indeed is also Kyiv, then I get one hour behind.

I would like to have a unified calendar that when an event is added to my gmail or outlook calendar it gets copied to the unified calendar.

Is that possible?

The attendees I select are not receiving their invites to my calendar events. My version of Thunderbird (TB) is 115.9.0 (64-bit). I check my sent folder and it does not send. Older versions of TB, the Calendar invite worked and I can see it was sent from the sent folder. Please note that I am not tech savvy and I need a solution that an average person can employ. If someone has a solution, please get it in step by step instructions and assume I know next to nothing.

There is no way to create a recurring task in Thunderbird - it seems like they are simply not supported. I've set the synchronization with my Google tasks but when trying to finish the recurring task through TB the synchronization error appears like I've updated the task on the server. Are there any plans to support recurring tasks?

Clocks went back one hour in Santiago, Chile last week and Thunderbird does not recognise the new time, although Windows (10) does.

The calendar line show the current time to be one hour ahead of the time on Windows; i.e., the Windows time has updated correctly, but the calendar time has not. Adding non-local events to the calendar causes them to be displayed one hour ahead of the correct time.

Changing the calendar setting to use the system timezone, or use America/Santiago has no effect that I can see.

Typing Date() in the error console of Thunderbird gives the correct time, as per Windows.

This also happened in the last time change here in Chile.

How can I fix the Calendar to see the same time as Thunderbird and Windows?

Hello, In Thunderbird (Vers. 115.9, OS Linux Zorin OS 17) I can integrate a calendar from a Mailbox.org account as described here(https://kb.mailbox.org/de/privat/adressbuch-und-kalender/caldav-clients-outlook-thunderbird-macos-evolution-kontact/). Everything works fine. If I now want to import a 2nd calendar from another mailbox.org account, this does not work. I can go through the process normally, but the 2nd calendar is not displayed. Does anyone have the same problem? It can't be that Thunderbird is not able to integrate 2 calendars ? Many thanks for your help

can i shut it off this way I do not gnat encryption and i am using Norton a d i also use ccleaner and glary does this have anything to do with it

Hi, I have a nextcloud setup at home on my internal network. Whenever I am away from that network, Thunderbird bombards me with error messages because it cannot sync a specific calendar (An error occurred when writing to the calendar Contact birthdays! Please see below for more information.) This is the first calendar on the list of calendars so I think it just happens to be that one that causes the error. What I would like to do is have Thunderbird detect that it isn't on my home wifi and not sync the calendars. Is this possible? Thanks!

Thunderbird's Calendar displays time for events from Google's calendar (probably other network calendars too) incorrectly. For example, i create an event with "New Event", select "Calendar: <my gmail account>" and set "Start: 15:00", "End: 16:00", then "Save and Close". Thunderbird Calendar displays it as from 16:00 to 17:00. "Use system timezone" is selected in Calendar settings. When i open "Edit" dialog for the event, time in "Start:" and "End:" fields is also incorrect (16:00 and 17:00 respectively). However, when i go to "Options" and click "Show Timezones" it becomes correct (15:00 and 16:00). Disabling "Show Timezones" leads back to incorrect time. Web page and other applications display time for the same event correctly (as i set it during creation). The same error for events created not by Thunderbird but on web page or other applications. Thunderbird 115.9.0.

I selected 'New Calendar' and my personal and shared calendar disappeared. I selected show all calendars but they are gone. I rebooted pc but still nothing there. Thunderbird 115.9.0

On my new laptop I can't get convert to task working. When I click on this option nothing happens. Convert to event works fine.

This functionality works fine on my desktop PC
