Thunderbird Community Forum

I was browsing this page: https://support.mozilla.org/en-US/kb/adding-a-holiday-calendar

Which says:

• Select "On the Network", and click "Next".
• From the Format list, select iCalendar (ICS).

But when I select "On the Network" I see no options for file format (TB 138).

Is subscribing to remote ics files still supported, or must we download the files locally and subscribe to them there?

Hi,

Someone sends me a calendar appointment for 11th of May at 16:30-18:30 and another at 18:30:20:30. I accept these appointments. In my calendar, they correctly display at these times.

When I close and re-open Thunderbird, the first appointment is now scheduled for 12th of May, but the second is fine. When I close and re-open Thunderbird again, the second appointment is now scheduled for 12th of May as well.

The times are completely different too.

I'm using Thunderbird 138 from the Arch Linux repositories but I've also tried the Flatpak package to no avail. I've tried setting my Timezone manually and using my System timezone to no avail.

GNOME Calendar, which is also synced to my Caldav server, displays the appointments at the correct day and time. The web interface for my mail server also displays correctly.

It's only Thunderbird that screws it up time and time again.

This has been going on for years and it is driving me insane. I can't use my calendar with Thunderbird because I keep thinking my appointments are at the wrong time!

Send help.

I successfully subscribed to an online .ics file but I found the resulting calendar entries inadequate and I want to unsubscribe but I can't figure out how to do that. I've tried searching for instructions but haven't found any.

An error occurred when writing to the calendar CanadaHolidays! Please see below for more information.

On calendar properties changed to read-only, still cannot import? Graham

Hi All,

Two days ago, my Google calendar sync stopped working. I tried to add them again, but now, for a change, I can't see events at all, even though Thunderbird plugins theoretically got access to calendars. Should I wait for an update? Is this a global problem? How can I solve it?

Thank you Mariusz

Get Messages doesn't work anymore. I created another profile with the same email address and it works fine. The issue is that I lost all my info, addresses, and most importantly the Calendar. I've been messing around with this all in trying to import that info into the new profile, but failing. I copied calendar-data to the new profile, but it doesn't show up. Can someone please help! Thanks, Paul

I'm just starting to use Calendar in the latest version of TB. I see that you can add little category color bars to each event. I tried to add a new category, but it disappeared from the dropdown menu as soon as I added it and a color bar never appeared in the event on the calendar display. How can I add and subtract categories? Can I change the colors assigned to categories?

I've had thunderbird for years, for the task component. It's wonderful. I got a new computer, but now have lost all my recurring tasks. I saved the profile on our network but cannot locate where to put in the path so import the task file into thunderbird. I did not find it in the community forums; so I must not be asking the question right. Any assistance is helpful.

Thank you

Hello and THANK YOU for Thunderbird and I am looking so forward to getting off Outlook! I am about 4/5 way through setting it up on my desktop.

I currently keep my calendar on Outlook. I have been able to import my folders, contacts and mail, but when I go to import the Calendar, the box on import cannot be selected. Is there something else that I need to do to bring over my calendar? Did I miss step when I did the initial set up?

import calender not working on new laptop windows 11. I have all my emails but no events show. i tried to import from your app but got an error message, I copied the calender export to a key but I still get the error message and the new calender has no events.

I have 3 Google calendars added to Thunderbird. After every startup I get a popup with the Google authorization page for every calender asking me to authorize access. I already tried removing all Calendars, cleaning the cache, resetting all calendar/google related settings in the config editor and readding teh calendars.

Is there a way to avoid the reauthorizations after each startup and have Thunderbird access permanently authorized?

There are no add-ons except Owl for Exchange (needed for my work outlook account) and Compact Headers.

Thunderbird is version 128.6.1esr on Ubuntu.

I am trying to create two separate calendars in Thunderbird. I would like one calendar to contain holidays, birthdays, etc. The other I would like to contain a list of daily tasks to be completed. I started by creating the holiday/birthday calendar and was mostly successful. I figured out how to create a new calendar; however, I do not know how to make it blank so that I can start adding my to-do lists. The new calendar appears to be a duplicate of the first calendar, with all of the entries I had put into the first calendar, instead of a new, blank calendar on which to make new entries. How can I make a new blank calendar?

Hello, I want to change first day of the week to Monday (who on earth would have Sunday as the fist work day??) Problem: All instructions online are useless since there is no "Options" / no "Preferences" / in Settings there is no "Calendar" or anything referring to Calendar. Under Settings there is only General, Composition, Privacy & Security, Chat and Export for Mobile. Nothing for Calendar. Also in Calendar view ... nothing to change days order. All online articles seem to be outdated (2021 and older)and don't apply anymore. Someone advised the reboot Thunderbird ... ? How to do that? Just close it down at the X?

Please help.

Thanks

I updated from TB 115 to 116. I had to re-enter email and calendar (to Google) connection info. Calendar does not display. Email and Contacts seem alright. Is Provider still needed?

I FOUND no close TOPIC.

Google calendar allows color-coding of events - but the display is highly inadequate. T-bird 128 calendar apparently HAS no option to color events. But events are FAR easier to see WHEN color-highlighted. Would this be a difficult option??

For years I have used the extension 'Calendar Tweaks' because it colorizes the entire event in the calendar. This extension is no longer compatible with versions of Thunderbird after 74 so I have stop updation after Version 69. However in resolving problems with authorization I needed to update to the current Version of Thunderbird so my events in the calendar now just show the category color at the edge of the box instead of the entire box. Is there a way in Thunderbird to colorize the entire event box or another extension that does this.

Like the subject says 'updated from 115 to 128.1.1esr and now (icloud) calendars wont sync'

I understand tb doesnt need tbsync anymore, do i remove these? When i try and enable the calendar function, a 'authentication required' windows opens up with username and password. But fails when the correct information is entered. I read where you can go to google, which i did, and get the required information, but that fails also.

How can I sync the new 128.1.1esr with my icloud calendars?

Thanks!

My Thunderbird profile is on a separate drive.

I had to reformat my computer. No problem with managing profile and all emails and folders, etc are ok. However, my calendar is blank!

Is the calendar not stored in your profile? Have I really lost all my dates and appointments?

I am using Thunderbird Supernova and am pretty happy with it. However, I cannot figure out how to specify a different time zone than the system timezone when creating an event. For example, if I just bought a flight that departs at 4PM London time and I am in Miami when creating the event, how can I create this event without having to convert that time to my current time?

Surely this is possible but I can't figure out how. Thanks for any help!
