Profiles was bad enough, as Thunderbird can never open the zip file (the wording of the alternative method is gobbledegook, and there are no recognisable files if you attempt to decipher it). At least you can set all your email addresses up manually - you can't physically re-types five years of calendar entries. The infuriating this is that when you start the import, the calendar entries appear before your eyes for up to five seconds and then the program crashes ... again and again and again. I must have been trying this on and off for years now and still nobody has fixed it.

I'm using thunderbird 115.10.1 on Ubuntu Linux. I've set up a second calendar and associated it with an email account hosted by Polaris Mail. That email address has worked fine within thunderbird for everything else for a long time, but I only recently associated it with a calendar. When I get a meeting invite, for example from a gmail user, and accept that invite, selecting "send a response now", no message ever arrives at the email of the inviter and no email ends up in any of my folders (drafts or sent). It is like nothing happens. The event *is* accepted and added to the calendar, but no respose is created or sent. I have another email account and calendar and meeting acceptances and responses seem to work fine.

I've looked at all the settings I can find and they seem appropriate and analogous to those with the working email/calendar. The correct email address appears in the calendar properties opened by right-clicking on the Calendar and selecting properties.

Any help? Thanks.

Hi,

Scenario: I have a custom domain with an email address, and have used mailbox.org and currently icloud to host my email. In both cases, the email address associated with my custom domain is the only one I use for everything, such as email, calendar, contacts, etc (x@er.com). Also in both cases, there is also a login email address to the email hosting service (i.e. x@mailbox.com and x@icloud.com respectively).

Issue: My calendar invites erroneously send from my icloud email address, rather than my custom domain email address. This appears to be by defaul and unchangeable. See 1/2 screenshot.

Settings: I'm on W11 Pro, using TB 115.10.1 (64-bit). For calendar settings, see 2/2 screenshot.

Background: With both providers, my calendar invites initially were being sent from the correct email address (x@er.com), but inexplicably switched to the being sent from login email address of the email hosting service after some time (about a year with mailbox.org, and a couple of months after migrating to icloud.com). This messes up my calendars, and I need to resolve it. Hopefully it's just something dumb that I'm doing.

What I've tried: On mailbox.org: When the issue first occured I put up with it for a few weeks then assumed it was probably mailbox.org and migrated to icloud. This appeared to resolve the problem at the time. On icloud, my calendar sync was setup in TB using add-ons, which worked for a couple of months and then the issue recurred. I've tried: 1. In apple account settings: I tried changing my apple-id to be my custom domain email address, rather than my icloud email address (didn't fix it). 2. I then unsubscribed from all of my network calendars in TB, removing the addons and restarting TB, as per https://support.mozilla.org/en-US/questions/1406255#answer-1568028 - I had to add a blank local calendar first before I was able to remove all of the network calendars. 3. I then added my calendars back into TB by using the direct URL locations, as per https://support.mozilla.org/en-US/questions/1406112 - when adding the calendars back, I tried using the login as both my custom domain email address, and also my icloud email address (didn't fix it).

Any help would be much appreciated.

Thank you.

I'm setting up TB for the first time with multiple email and calendar accounts. Some are gmail / google, and others o365.

The primary TB account's calendar doesn't seem to be syncing fully. It's an o365. account. But the email is working.

I added an event on my Outlook for Android on my phone. Its appearing in OWA, and in New Outlook on my computer (so it did sync from mobile Android device to server, and from server to my New Outlook on the Windows desktop). But its not appearing in TB.

Not sure what to check or what the issue might be.

Also, I'd love to replace Outlook Android on my mobile with what I think is K-9. But can't get the same account referenced here to connect to the outbound server.

Welcome any help, and appreciate you all doing this collaborative work.

Hi Everyone!

I am currently on Thunderbird 115.10.1 (64-bit) and for a few days now, I can't open the calendar tab. The "Today Pane" is working and showing events though.

When going to "View" the items "Calendar" and "Tasks" are greyed out though.

Any idea on how to get the calendar back? The company will move us all to Exchange and Outlook soon, so I thought I might "survive", but it is pretty impractical have to open my calendars separately in the browser. You only notice how often you use something, when you don't have it. ;-)

Problem: I'm 76 years old and technically self-taught. I have 2 Windows 11 computers. One desktop and one laptop. Both are fully updated and utilizing Office software, specifically Outlook. Not too long ago I happily discovered Thunderbird and like it soooo much better. QUESTION: Within Outlook, my calendar is displayed as iCloud Calendar which is ok for me. The one thing that is keeping me from exclusively using Thunderbird is not being able to import my iCoud calendar into Thunderbird. Is that even possible and if so, how? Please keep your response as simplistic as possible. Thank you for your time and consideration given to my inquiry.

Hi Team,

I recently started using THunderbird as an inbox and calendar tool a new business we have started with my team. I have a couple of questions.

1. I have the e-mail app on my android phone, but how can I get thunderbird calendar on it? 2. My other two businesses use google domain and e-mail accounts and my personal calendar is also on google. How can I sync the thunderbird calendar with my google calendar, so that events which I create, receive, accept on one of the calendars (i.e. Thunderbird) will automatically appear on the other (i.e. Google). 3. And is there a way to sync the calendars so that I can edit calendar events from everywhere (regardless of where they have been created)?

Thank you in advance.

Kind Regards, Alex

How does one enable calendars in Thunderbird version 115.8.0? When I click the calendar icon on the left of the page, I get a calendar displayed but it has a message highlighted in yellow that says: "All calendars are currently disabled. Enable an existing calendar or add a new one to create or add events."

I cannot find anything in settings or elsewhere to enable calendars.

TIA

Hi lads,

I used TB for many years but only now started using it in office. I have a problem with the calendar function however which I have to use now. I'd like to have an audio alert and/or window pop-up forcing interaction for any event in my calendar, let's say 15 min ahead. I tend to overlook the small notification pop-ups in the bottom right corner of the screen since they also vanish automatically after a few seconds.

I can get these small bottom right corner pop-ups to appear for any event by using the global notification preferences in the Edit Calender options. However, I can not globally activate an audio alert or a window requiring interaction for upcoming events. I can just activate a reminder manually for each and every event, which is a lot of work, naturally. So, is there a way to activate a reminder (not a notification, which is the bottom right pop up I assume) globally for any event in a calendar?

Can also be done by an add-on or by manually changing source files, if anyone has suggestions in this direction.

Thanks in advance, trashmaster

I have recently become a Thunderbird user (115.5.0), and have linked it to my gmail account for email, calendar and contacts (and tasks, but that does not seem to be working).

My calendar within Thunderbird shows a recurring daily event which does not appear in my Google Calendar. I'm not sure how to resolve this issue.

You can see on the attached image, on the right is my google calendar which Thunderbird is supposed to be syncing with, on the left is the Thunderbird calendar, which has all these extra recurring events.

Any thoughts on how to fix this would be gratefully received.

thanks in advance,

Keith

When typing up event comments, in Calendar, the spellchecker highlights incorrect spellings but does not offer alternatives when the word is right-clicked, as the email composer does. This has become rather annoying and one other user asked the same question in November 2023, but never got a response. That particular thread has been archived, so I can't add to it. Can the developers please look into this?

Thunderbird 115.6.0 (64-Bit) is no longer syncing with Google Calendar.

I do not know since when, but recently added dates in Google Calendar are not show in Thunderbird calendar and vice versa. 

I've tried to setup new connection between Thunderbird and Google, this seems to work, because I got question on smartphone (authenticator app) to allow new connection. But the dates are still not synced. Even forcing sync does not do anything. Same things happens on two Windows 10 64bit computers, but also on Linux Mint. Any advice? Thanks.

In setting up a new phone, using BirdieSync to synchronize Thunderbird Calendar with the phone, Calendar ended up with duplicate events, but only those that had originally be setup using the "Repeat" button in the "New Event" window. (Ex. a class that meets the same time, same day, each week.)

I cannot find any way to locate and batch delete the duplicates. This seems like it should be basic functionality for a digital calendar. Is it really missing from Thunderbird or am I missing some obscurely located "Delete Duplicates" menu item?

Something changed at some point in time with the calendar file. When I started using Thunderbird I was able to set up entries in the calendar file and give them names and an associated colour. I can't seem to do that any longer. Eg. I set up entries for Birthdays which showed on the calendar as purple and Anniversaries where green. I can't do that anymore. Was that ability removed at some time?

Another situation I came across was importing .ics files. The method changed and now you have to open a file. What it does is ask where you want to put the contents, ie as an Event or a Task. I tell it where I want it put . But when I check the entry it shows as the .ics file and not as an Event or Task. Then I have a terrible time trying to remove it. Nothing happens when I tell the program that the Event/Task is completed. HELP!

I posted a question to the help community but I don't know where to see if anyone responded. The question had to do with how to sync my Windows 11 Outlook calendar with my Thunderbird calendar.

Wenn ich den Wochenkalender ausdrucke erscheint nie der Wochentag (Montag, Dienstag usw.), obwohl diese auf dem Bildschirm in der Wochenansicht zu sehen sind. Leider finde ich keine Möglichkeit, dies zu ändern. Können sie mir weiterhelfen? Mit freundlichen Grüßen Gerhard
