I just updated to 102 and lost calendar. I tried instructions from your help page. Got as far as "extensions.installedDistroAddon.{e2fda1a4-762b-4020-b5ad-a41df1933103}". What I see is that boldface in a box with True further to the right and then a toggle and delete icon. When I right click I only get a box that says copy, paste or select all, with select all being the only option available. I tried toggling to false and then continuing. When I go to the add on manager and select extensions, there are none listed. I tried restarting Thunderbird at that point, but the calendar is still not showing my info. Help!

Hello this morning Thunderbird Updated in Germany to Vers. 102. At vers. 102. Calender shows no categories in Google Calender or Web.de Calender.

I have added TbSync and CalDev/CardDev to each of 3 Thunderbird Lightning accounts and have set up 1 account on woelkli.com (their cloud area). I had hoped that adding a calendar event on any one of the 3 Thunderbird would then be replicated in the other 2 accounts. This does not happen and I am unsure what I need to do to make it work. Please could someone advise me. Thank you

OK, TB is driving me crazy with two Zoom events (plus others in the past that I just had to delete because they were so annoying.)

Whether I click "Dismiss All" or click on the individual event and "Dismiss", they pop right back up. Same thing happens when I try to close the window.

I have removed mail extensions (Provider and another that I can't remember the name of), deleted the calendars, restarted TB, and added the Google Calendars again... but they still pop up.

And, again, this seems to only happen with Zoom events but not all Zoom events... not even all Zoom events on one calendar.

Finally, the calendar is not set to Read-Only.

This is driving me crazy because not only can't I Dismiss them, they also beep every five minutes. Right now I have to disconnect the Calendar before I lose my sanity.

Hello, 24hrs time was working fine with former Thunderbird. 24hrs time disappeared from calendar when installing Thunderbird 102. In Windows 10 clock: time is correctly set to 24hrs. No way to install 24 hrs in Thunderbird 102 settings. How manually set windows 24hrs time with Thunderbird config? Thank you.

I´m using TB 102.0.1 in Windows x64 Professional. I have config TB to work in English (menus, notifications, etc.), but with this update I have to change to Spanish language to allow the 24h format in Calendar. Every time I change to the Regional setting (Spanish) from an English language the Calendar change to AM/PM format, when I have config Windows to 24h format (HH:mm). I have always config TB to work with English menus, but I lost this possibility with the last update. Windows 7 Professional work with an Spanish language installation, and I suppose that in this new version of TB something has change with the Language/regional configurations. Is there any possibility to select the "time format" of the Calendar (24h to AM/PM or AM/PM to 24h)? Thanks

As mentioned in title I cannot use the calendar function at all. Same with tasks function:

• I can open the calendar tab, but that's it.
• There is no calendar on the calendar list, and the 'plus'-icon to add a new calendar is greyed out.
• There are buttons to change the views (week, day etc) but these also are greyed out.
• Same issue with tasks: I can open the tab, but cannot add any tasks

It all worked with older versions of TB. I had several calendars in place, no problem. But after some upgrade everything is gone. The calendars, originally set up on TB, are still there, but only accessible on the g-account...

Version: TB 91.11. Add-ons: Provider for google calendar

Any idea? I really want to use TB calendar function instead. If I could at least only set up a new calendar, that would be very helpful. Thx a lot in Advance!

SEE attached annotated SCREEN-SHOT file (Tbird ICS file process.jpg)

Is there any way to process this .ICS file ... "Upcoming Appointment (4).ics" ... directly into the Thunderbird calendar as soon as I click on the link-phrase "Add to calendar" ... without having to save it first and ... then double-click on the saved file ???

How can I submit a defect for Thunderbird / Lightning calendar? I'm not sure about using Bugzilla myself.

I was typing a bit fast and accidently entered 4 chars for the year on a new calendar event and saved it. After that the event vanished from the calendar. I used Events and Tasks > Find events to locate it but when I clicked on it Thunderbird crashed.

I had opened a ticket before (https://support.mozilla.org/en-US/questions/1354662), and got "some" help, tho it was still happening intermittingly, until recently, when it resumed in full force. https://www.screencast.com/t/3sFZdgMyt

I am not running the "Provider for Google Calendar" any more. I did a Google login and asked it to find my calendars, which it did. I have 13 calendars being displayed on the calendar tab. My version is 91.11.0 (64-bit), and yes, I am aware there is a newer version (102) but some of my clients who I recommended Thunderbird to are on it, and hate the new changes and are having trouble with it scrambling email content, cross linking a subject with another email when opening and the like. I won't be upgrading until those problems are resolved.

I am on a new laptop (since the last support ticket) running Windows 10 Home. I keep my Windows up to date and security patches installed.

Processor 11th Gen Intel(R) Core(TM) i7-11800H @ 2.30GHz 2.30 GHz Installed RAM 64.0 GB (63.7 GB usable) System type 64-bit operating system, x64-based processor Pen and touch No pen or touch input is available for this display Edition Windows 10 Home Version 21H2 Installed on ‎6/‎11/‎2022 OS build 19044.1826 Experience Windows Feature Experience Pack 120.2212.4180.0

Any help or additional suggestions are welcome. I'm being driven crazy by reminders that won't cancel.

My Thunderbird Calendar has started displaying time in 24-hr format (HH:mm), while by Thunderbird eMail continues to display the ‘am/pm’ format (hh:mm tt), correctly using my laptop’s Windows 10 System format, as shown in Control Panel/Region/Formats tab. I’d like to get Calendar back to hh:mm tt, without loosing all my calendar data. I suspect the problem was caused by an interruption when downloading the latest Thunderbird update, so I’ve tried manually downloading and installing a fresh copy of Thunderbird Setup 102.0.3, but the time display format wasn’t fixed. Is there a reliable way to roll back to the previous version without losing what I’ve added to my calendar between the time this format change occurred and the time I first noticed the change?

I have just moved from Outlook and I have converted my PST calendar to ICS. When I try to import the ICS file, nothing happens.

The JPG shows where the import stops.

Is there a solution and if so, how do I fix it?

I don't want to have to keep Outlook around just to use its calendar.

Thanks for any assistance.

I am no longer able to import iCalendar appointments I receive via email. Add-ons installed: Google Cal Plug-in, Open Google Cal, and Provider for Google Cal. Disabled (now incompatible): TbSync, gContactSync

I have attempted two approaches: 1. +Add from the email (attachment) itself 2. Save to desktop and then Events & Tasks | Import...

Thank you, Mike

Hello. I wanted to ask you about the option of switching between calendars in thunderbird I have two gmail accounts and I mainly use one of them altogether with the calendar. Thunderbird automatically loaded the calendar from the other account. I tried to switch it by going to Edit - Calendar preferences - and marking the right calendar account but it still didn't work. How do I do it? I also change the language but somehow the actions don't apply. Is there an option how to save the changes I am making?

Hi community,

I am looking for the way to change the start of the week to Monday. The default is Sunday start, but I can't find a way to change it so far.

My thunderbird version is 102.1.0 (64bit) for windows.

I will appreciate your help.

Thank you in advance, KT

Hi there,

the event time selected during event creation has the 24 hrs format I want, but the calendar after it has been created shows it with 12 hrs format - see the uploaded image: is there any way to fix it?

I'm running Thunderbird 102, 64 bit, fresh installation (not upgrade) on Win 10.

Thanks in advance.

Hello,

After upgrading to Tb 102.0.2 calendar (Lightning) is not following "Date and Time Formatting" setting. Anyone knows how to fix it?

Thanks,

JM

I followed the instructions here: https://support.mozilla.org/en-US/questions/1364439 After pasting in the URL of the Google Calendar from the browser, the process asks for the password used for the Google account. I provide the password, but the response is "The credentials you have entered were not accepted."

To confirm that the user name (my Gmail account) and password were entered correctly, I logged out of Calendar on the browser and logged in again using the credentials that were refused by the Create New Calendar process.

This isn't a showstopper, but it would be nice to have the calendar in Thunderbird.
