Problem with recurring events in the caldav (external) calendar. If you delete one instance of an event (today), events for previous days are automatically created.

Thunderbird ver. 140.7

For many years I have had a Thunderbird Calendar, and have a large number of Tasks set up in it. I have now decided it would be convenient to link it to my Google calendar, so that it also shows on my new Windows 11 machine and on my laptop. I've gone through the process described in the "Create new calendars" article, to link the calendars, and the Google calendar is now appearing in the Thunderbird calendar, but not vice versa. How do I get the Tasks in the Thunderbird calendar to appear in the Google calendar?

I am running Thunderbird 140.7.1esr and Firefox 147.03 on my Windows 10 machine, which I used to set up the link. My Windows 11 machine has the same Firefox build, but Thunderbird 147.0.1, and the Google calendar display is the same, but I haven't yet set up the Thunderbird calendar on the new machine.

I have been using ThunderBird on Linux Mint for some time now. I am using Outlook.com for emails, calendar and contacts and I sync with another laptop and mobile phone. All fine until a few days ago when I noticed calendar events were not syncing with my phone. I found one calendar event in ThunderBird had an error when I manually synced with TbSync. The error report did not say anything specific. I deleted this calendar event and TbSync ran successfully uploading 2 events that it had not uploaded due to the calendar sync error. I then wanted to manually recreate this calendar event in ThunderBird. When I clicked on "New Event", the Calendar New Event pop-up window did not appear. When I minimised the ThunderBird window, the New Events was not behind it. The ThunderBird icon pinned to the panel had a "2" in the corner. When I hovered over the ThunderBird icon in the panel, it showed both the ThunderBird window and New Event window preview. When I selected the New Event preview window in the panel, it still did not become visible. All I could do with with New Event preview window in the panel was click in the 'X' to close it. I checked for Lightning Calendar Tab add-on updates. It was up to date. I check the settings. All OK. I disabled and enabled this add-on. Still not working. My Windows habits made me shutdown and restart my device. Still Not working. When I checked the other ThunderBird functions, New Event pop-up windows appeared for Emails and Contacts but not Tasks which had the same symptoms as the Calendar.

(Sorry, there is no calendar topic ... but this is about converting calendar event to email message...)

I just discovered (because I needed it for the first time) the nice and useful "Convert to ... message" feature for calendar events.

The converted event does not, however, include the date and time of the event nor the location, arguably the most important information about a calendar event. The calendar it is located in would also be handy, for those of us maintaining multiple calendars. Currently, it places the event title in the subject line, and the description in the message.

Anyone know if this is configurable? I looked in settings and didn't see anything.

Most useful would be a default template, which users could customize, perhaps per-calendar. All that I can see that is customizable about this is the sending email address, which can be set in the calendar properties.

Another issue is that this feature is not available from the event detail popup. In that case, I would think it would be not only available, but prominent. The event detail view is where I would expect most features relating to an event to be located, yet only the "Edit" button is present.

Hello I searched the help articles and was surprised I could not find anything on this. I receive different calendar entry files, in this case a .VCS calendar file, from services I use to use as a calendar entry i.e. a reservation or other. I am able to import this file and create the calendar item in Google Calendar, however if I am on Thunderbird Calendar, I have been unable to discover a way to import. Am I missing this function? What are the steps needed to import a VCS file into Thunderbird Calendar? Thanks Mozilla community! -kozy

if I type a hyperlink into the Calendar description field it does not link to the url.

The mouse pointer does not change from a cursor to a pointy hand when I hover over it

I have also tried using the 'Link' button and that creates a blue/underlined url like a traditional clickable link but the result is the same as before.

Please help troubleshoot the problem, at the moment I'm having to copy and paste every link which becomes tedious when there are lots of links

Thanks

I hope I can explain this well: Recently, many recurring events from Google Contacts, namely birthdays and anniversaries, now appear in Google Calendar as invitations from "Unknown Organizer <unknownorganizer@calendar.google.com>" that I have accepted (but I have not.) These events keep triggering pop-up notifications. Those notifications do not respond to the Dismiss or Snooze buttons - they do nothing. I can dismiss the dialog box with the upper-right [X], but the pop up gain every time the calendar re-syncs. I try to edit the properties of the event, but the changes do not take. When I look at Google Calendar directly with my browser, these events do not show up, only the proper ones that are listed in my Birthdays calendar.

Why did this happen, and how can I fix this. The un-dismissable notifications make Thunderbird Calendar unusable. I find many similar (but not necessarily identical) complaints going back years, but no actual solutions.

Two questions:

1- Is it possible to assign defaults for ICS import so that you don't have to go through the wizard?

The reason for this wish is question two...

2- Why does the "Next" button in the import wizard appear in a different place in each step? I have a whole bunch of separate ICS files to import due to a workflow issue, and importing them is like playing whack-a-mole. It'd be a huge improvement if the "Next" button could stay in a consistent place so that even if defaults can't be set up, you can just click-click-click in one place without having to dance around with the mouse :)

In the past week or so (since the holidays, perhaps), meeting invites I am getting are not converting the time correctly. I can make it work by manually editing the ics file and changing the first TZID from America/Chicago to US/Central I. The screen SHOWS the correct time (image atached) , but it imports as it the time was UTC

If the DTSTART and DTEND are set to US/Central it doesn't work. The issue is it would seem that the user is creating these with the webmail version of Rackspace email, which he has done for YEARS with no issue. Did something change as of recent that would make this format no longer work?

I have to export every one of his meeting invites (and several other people not using rackspace) and make that change at the top to make this import correctly.

Hi, my name is Rob and I have been using Thunderbird now for 3 months. Love it. There is a nagging issue. I have 2 gmail accounts. They both show events in the calendar. However one of my accounts when showing a reminder for an event, will not allow me to "Dismiss" it. Only solution is to close the dialog window. It shows the organizer as "Unknown organizer...." The other account works just fine. Any help is appreciated. Happy new year. Thx

Thunderbird v 141.0 64 bit on Windows 11 Hope you can help. I have my main Thunderbird calendar synced with a Google calendar. When I created the sync, the Thunderbird calendar was populated with all the events in the Google Calendar. When I created a new event in the Google Calendar, it appeared in the Thunderbird calendar. When I deleted a recurring event (that originally created in the Google calendar) from the Thunderbird calendar, it was deleted in the Google calendar. All good! But I have created multiple events in the Thunderbird calendar, but they are not appearing in the Google calendar.

Any thoughts? Thank you so much. Best, Stuart

Nach Update auf Release Kanal kein Geburtstagskalender mehr und Geburtstage werden nicht im Kalender angezeigt. Geburtstage in Kontakten vorhanden. Benutze keine Cloud und kein Google. Wie werden Geburtstage wieder im Kalender angezeigt?

Windows 11, Thunderbird 140, How to increase the"New Event" box and its Font

- Windows 10, the size is OK

- I have 'Googled" this problem and there seems to be no answer.

Kind regards: Gary Shaw

I don't know if something has changed since the last time I downloaded a .ics file into thunderbird or not.

I used to be able to load a .ics file directly into 'events' in my calendar. But something has changed. When I download the file now it gives it the name "Zul52mNeovl5. Which happens to be the name of the file I'm downloading from. So now I have 3 options of where to put the file - Events, Tasks or this filename. I can't find this file anywhere on my computer. How do I get rid of it?

Any Help would be appreciated.

Thanks

Hi, my Thunderbird calendar reminders are coming up 4 hours after the meeting.

Running Kubuntu. System locale/timezone OK, TBird set to use system time (though manually making it the same didn't help). HW Clock matches system time. Pacific/Auckland.

Tried exporting all my appointments and re-importing them - no change.

Hello everyone,

like the title says, I want to set appointments in the calendar to private. I have shared calendars. Therefore, I need to be able to set some invitations to private.

In Outlook, it's no problem to set an accepted appointment to private, but in Thunderbird, this option only seems to be available for appointments I have created myself.

Hello,

I created an event in the Thunderbird calendar, inluded 30 e-mail addresses of which only 19 calendar invites were sent. It sent the invites in the order of the recipient list and just stopped at number 19..

What could be the problem here?
