Thunderbird Support Forum

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?

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?

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

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).

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

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?

I cannot dismiss calendar invites sent to me from others on the Ubuntu platform. I can dismiss invites that I have initiated. FYI this doesn't seem to be the case on the windows release - I can dismiss "foreign" invites.

The only way to dismiss these invites is to delete them from my calendar (which I prefer not to do). Thanks.

According to thunderbird, this event starts at 10:30 (second image) and runs until 11am (end time is correct.

Google calendar correctly has this event as starting at 10:00 (first image) running until 11am. This event is synced with google calendar and my outlook calendar (outlook has it as 10:00 as well).

It's not a time zone issue because the start time is off by 30 minutes and the end time is right. Any idea what's going on?

(Clearly a calendar sync that gets the times wrong isn't so useful.)

I have a calendar event with multiple people set up. I want to add a person to the event and only send a new invite to the new person (and not send a second invite to the original invitees). Is this possible? thanks.

Hi,

I recently installed a CalDAV server at my workplace to connect to in the Thunderbird calendar, as we all already use Thunderbird for e-mail.

If I create a meeting in the calendar and invite everyone else, they all get an email invite with the name, time & place of meeting etc.. And at the top of the email, just below the title of the email, there is a purple bar with boxes saying "Accept", "Tentative", "Deny" and "More" (or something synonymous, I have it in Swedish).

For one employee that purple bar with the "Accept"-box does not appear, and the only way for him to get the meeting to his calendar is by downloading the "invite.ics" file that is attached and importing it afterwards.

I have added two screenshots showing what I mean. One with the Accept, Deny etc. and the one person's e-mail that doesn't have the boxes.

We have checked his settings without finding anything that seems wrong in first glance. I have checked the caldav user account but the user account has the same settings as the others. Thunderbird is updated to the latest version (115.7.0, same as I use and it works for me).

When he invites people to a meeting they all get the invite correctly, so nothing is wrong when he creates a meeting invitation, only when he recieves an invite.

What could be wrong? Is there a setting he might've activated/deactivated in Thunderbird that we missed when looking or could there be something else we have thought of?

Thanks, Tim

When scheduling on Calendar, it is set to "Contacts," and I have to manually click on that box and change it to my e-mail each time I schedule something. I can't find how to make my e-mail the default. Help?

Ever since the latest 115.8.0 update local links to .pdf file stopped working eg: below. When I would click on that link it would open the invoice.pdf in my PDF client.

file:///D:/%20Internet%20Services/%20Feb%20invoice.pdf

Hoping whatever was broken will be fixed soon Thank You

It has been about a week now since 115.8 tried to install on my Windows 10 but could not without my password. I have been on Auto update for years now and could not put in correct password. It was suggested I go back to 102 and start over with a new account. I did. I have 102 and can send and receive emails. Problem is 102 does not show all emails that show in my same account when I log into Ionos.com host of my email account. I created another problem going to Thunderbird 102, birthdays. I have no access to my Thunderbird calendar not only for this month but all months this year and forever. I made a copy of everything in my account prior to going back to 102 to get a new password. How to I get my 2014 calendar back. And first thing I do if and when I get it back is to use a pen and paper to write down birthdays and whatever I want to remember and save it on paper just in case this happens again? Thanks.

Hi. I just started to use thunderbirdb calendar and I'm a bit confused about 'Tags.' Should I be able to add a tag to a new event or task? If so I see no option to assign a tag to an event or task.

How do I distinguish between an event and task?

Thanks, James

Given that I want to create a new event in the calendar with a description When I click on +New Event Then a tab opens that is so large given my 175% scaling that the Description field for the New Event is just above the taskbar. I cannot see what I am typing beyond the first line. There is no scrollbar to scroll down, nor a way to collapse the fields above.

=> This design is inadequate for 30% of the world population that suffers from presbyopia, or age related poor sight, and uses a large scaling.

Hi, When creating an event in the calendar view, I get my timezone displayed (Europe/Paris), I set my starting and ending time and save.

On event display in the calendar, I immediately notice that the time is off by 1h. On viewing the details, the right time is displayed but on 'Europe/Dublin' timezone. Changing it back doesn't fix the time, timezone always change after save.

I took a look at my settings, tried to use "use system timezone" (= Europe/Paris) of forced it to Europe/Paris, even checked the config editor, but nothing changed.

Did I miss a setting ?

My calendar is sync by CalDav (using TBSync), don't know if this could be related.

Thunderbird 115.9.0 (64-bit).

I have my timezone set to manual, Europe.

I create an event for 30 March 2024 and the time is displaying in my time zone

I mark it as ALL DAY and it switches to Local Time (not a problem so far)

If I display the calendar as 1 month starting with 24 March, then the event shows properly on Saturday 30 March

If I scroll the calendar up to start on 31 March, now the event shows on 31 March.

If I edit the event, it says the timezone is Chicago.

Changing the timezone and resaving it doesn't help.

Whenever I enter a new calendar event in Thunderbird, the calendar always defaults the event start time to 15 minutes after the hour, regardless of what time I'm making the new calendar entry. Is the new event start time a default setting and if so, how do I change the default to start new events on the hour, meaning HH:00 and not HH:15 which is what Thunderbird always defaults to? I use Thunderbird v115.9.0 (64-bit) for Windows, and the computer runs Windows 10 Home, v22H2, build 19045.4170. Please advise. Thank you.

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
