Thunderbird Community Forum

I have my calendar from mailbox.org synchronized with my thunderbird via CardDav/CalDav. I have multiple calendars in the same account (e.g. work, free time, brithdays, ...). I cannot change in which calendar an event is saved after I created it.

How to reproduce: Edit an allready existing event and change its calendar (e.g. from "free time" to my "work" calendar).

Expected behaviour: The edited event is now moved to the other calendar.

Observed behaviour: The event is not moved (any other changes to the event are saved though).

It is not the fault of my provider as it works on my phone and on their web app.

This is either a bug in any of two ways:

• It does not change calendars events but it should.
• You are not supposed to be able to change the calendar afterwards and that means the selection of the calendars should be grayed out/ give you no option to save it.

(I know I can Ctrl+X and Ctrl+V it into a diffferent calendar, which I use at moment but that costs additional time.)

Thanks for any help with this :)

PS: I have to choose a topic but the calendar is not even part of that list. What is going on there?

How do I import *.ICS file in a reasonable amount of time. I have appointments in an ics file of less than 1 K in size, typically 700 - 800 bytes in size and they take HOURS to import and do not connect properly then to allow editing the appointment. This is from Baylor Scott and White, a major hospital system in Texas. If there is a problem with the imported file structure, please point me to the correct file structure. I like Thunderbird, but this part of the calendar is very frustrating. Clarence

It seems lately that when I simply open a calendar entry to see what the contents are, then close it without making any changes, it sends an update to all those involved that something changed (as seen in the picture).

Also, when I accept an invite event and tell it not to send a response, it always does. This has been happening for as long as I can remember, and I cannot figure out a way to stop it, no matter what I do.

Anyone have any ideas for either of these issues?

I have a professional email address and a gmail address configured correctly in thunderbird. I also have a number of google calendars configured in lightning using the built-in google calendar support (i.e., I am not using the old google calendar plugin). Until recently, when I received and accepted a calendar invitation sent to my professional email address, thunderbird would ask to which calendar I wanted to save the invite. I would select the calendar I wanted and it would be saved appropriately.

A week ago, I created a new google calendar and added it to thunderbird/lightning using the built-in google calendar support. Now, when I accept a calendar invitation, it automatically goes to the new calendar (which is generally not appropriate) without asking me to choose. Furthermore, I am unable to edit these calendar events to change the calendar they are associated with. I have checked the properties of both the new and old calendars and they look the same.

The only seeming solution I found was to make the new calendar read only and disassociate it from an email address, and then undo both those options. For the time being, this operation seems to have gotten back the option to select which calendar invites are saved to. But I would still like to know if this was the correct solution and better understand how thunderbird chooses to save event invitations.

Bisherige Ativitäten: Versuche einen Google-Geburtstagskalender Kalender zu nutzen -> nicht funktioniert Versuche einen Mozilla-Geburtstagskalender einzurichten -> nicht funktioniert

Ich vemute, dass die entsprechenen Kalender keine entsprechenden Daten finden?!

Thunderbird und die Adressdaten stammen aus der gleichen Version wurden aber von einem anderen Windowsgerät unter Windows 10 übertragen/übernommen!V

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.

(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.

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

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

When syncing Thunderbird to Google Calendar, it creates two events for birthdays associated with Google contacts. Though it's not a critical bug, it does seem like after all this time it is something that should have been solved. Is any work being done to address this?

I've seen the workaround to disable birthday "Sync from contacts" in Google Calendar settings, but that removes the birthdays entirely from both Google Calendar and Thunderbird which is not really a solution. Thanks.

Downloaded the Thunderbird U.S. holidays to my calendar. My calendar is overloaded with miscellaneous and unwanted holidays. I've tried methods on the internet to delete them from my calendar with no success. I'm sure there is a method, but no success in finding it. Please help! Do I need to unistall Thunderbird and start over?
