Thunderbird Support Forum

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

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?

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.

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

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.

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

After importing events from the old ics calendar into the existing CalDav calendar. TB sent invitations out to all attendees, even for past meetings. How to avoid 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.

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.

When I double-click on an event in my TB Lightning calendar, the event details window/popup/whatever-you-call-it opens up at a fixed size which 90% of the time is too short vertically to see the Edit button. This forces me to have to resize it manually just to be able to click on Edit. This is making the calendar very annoying to do. Any of the following might help:

1. How can I change the default popup window size?
2. How can I make the manually selected size sticky?
3. Can you change the default size to automatically be tall enough for the Edit button to be visible?

Thanks for your help

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

Hello,

Similarly to user that asked https://support.mozilla.org/en-US/questions/1376333, I would like to know if an accepted event can be edited – really edited, not just by converting/duplicating it to a task or another event.

For example, if I added an accepted invite to the wrong calendar and would like to move it to another one of my calendars... This calendar switching feature is part of MacOS Calendar, even if, as in Thunderbird, other properties of an accepted invite are not editable (except for comments).

Since this lack of control over invite edition is mainly what is holding me to adopt Thunderbird, is such a feature likely to be deployed eventually?

Regards,

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

I use Thunderbird calendar for all my events and without it I am lost. Yesterday, I wanted to export my calendar to be imported later by an online platform. I used the export function. I noticed however, that under the name of my calendar on the left pane this has appeared ( . export). I thought the ics file is already created, so I went ahead and deleted the strange ". export" item that appeared under my calendar name in the left pane. What happened next was that all my events disappeared from my normal calendar window. My question is how I can get back all my events? Or how I can restore the ". export" so my events come back.

Additional information: I did not have backup for my calendar. I cannot locate anywhere the ics file I thought it is "exported" I am using the latest version of Thunderbird as of March 2024.

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

After exporting the Thunderbird calender, the tasks do not appear in the destination calender, only the calender entries. Is it possible to export/import tasks? Emclient was the destination email client.

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.

Having finally got fed up with all the adds in Outlook.com, I've now started using Thunderbird as my email client! (I know, what took me so long?!) I've set up my email ok and it all seems to be working fine and syncing with my Outlook.com account, but I have some queries regarding the Calendar. I've managed to add my Outlook.com calendar to Thunderbird, but; 1 - How do I sync my Thunderbird calendar with my Outlook.com calendar?

    At the moment any changes/additions I make aren't synced.

2 - Also, someone shares their calendar (Outlook.com) with me.

     How do I add and sync this to my Thunderbird calendar.

Although I love my tech etc, I'm only good with what I know, so please explain any solutions as clearly and simply as you can, sorry! Regards Mark

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.
