when I add to or make changes to thunderbird calendar on my desktop, it does not copy to my laptop. they are on the same network. can they both sync to new changes?

i have several calendars one being Home, RBSALES, BIRTHDAYS can I set one of these to be the default? right now the default is HOME which as far as I know I do not use it. If all my event are in RBSALES can I delete the HOME calendar? Thank you, Rick

Hi,

Thunderbird regularly unable to connect to my Google Calendar. Is there anything I can do? I updated it to the latest version today and now it said all the calendars (local, Google) are unavailable no matter what I do (unsubscribe, subscribe again and again)

And if I try to create a new calendar, the Google Calendar option is not even there anymore.

Is the latest Thunderbird broken or something I did?

Thanks,

Will

I'm attempting to add the public stream schedule for a Twitch streamer to my calendar in Thunderbird, which is possible because Twitch does offer an API endpoint to get a streamer's schedule via RFC5545-compliant iCalendar file (https://dev.twitch.tv/docs/api/reference#get-channel-icalendar). However, Thunderbird doesn't seem to be respecting the timezone information in Twitch's iCal data and it is not converting event times to my local timezone (America/Chicago). If I open one of the imported events from the iCal in Thunderbird in Edit mode and enable the Show Timezones option, Thunderbird appears to be interpreting the imported start and end times as "Local Time" instead of the timezone specified in the iCal. If I change the timezone in Thunderbird's calendar settings, the start and end times of the calendar events imported from Twitch do not update either.

This happens with ANY iCal from Twitch, but for the sake of illustration, the specific public calendars I'm attempting to add are: > https://api.twitch.tv/helix/schedule/icalendar?broadcaster_id=519794491 > https://api.twitch.tv/helix/schedule/icalendar?broadcaster_id=425292962

Other software (GNOME Calendar and the Open-Xchange-powered platform my e-mail provider uses) is correctly interpreting the timezone data in Twitch's iCal so the issue appears to be in Thunderbird. Any suggestions?

When several Lightning Calendar Reminders are in a popup window list, addressing one Reminder is causing some, or all, other Reminders in the list to vanish. This happens whether Snooze or Dismiss are selected for an individual Reminder.

I live in Morocco. At the weekend our clocks went back 1 hour. However, despite Thunderbird Beta being set to system time for Calendar, it is calculating the time as if my time had not gone back one hour. Any suggestions? Thanks in advance.

if I start Tunderbird I get the message "https://caldav.web.de verlangt einen Benutzernamen und ein Passwort". I have stored the password many times but it appears any time I start Thunderbird

Always the same bug and it seems nobody from MOZILlA is able to troubleshoot.

When I open Thunderbird, the following panel appears. I cannot delete it.

Authentification require -Mozilla Thunderbird" https://caldav.gmx.com ask for a user name and a password.

I never create this account

I want to sync calendars across Thunderbird and iPhone. (Linux Mint 22 Wilma, Thunderbird 140.14.1 esr)

I am trying to use the Apple calendar server to sync with. Using the Create New Calendar dialog box in Thunderbird, then applying the Apple-assigned password, Thunderbird returns "Could not find calendars at this location. Please check your settings."

I would appreciate help with this.

Hi everyone. I have setup Synology Calendar on my NAS, and I am now able to Sync my calendar across multiple devices. While events in calendar sync, I am unable to create tasks that will sync to all devices, and have the "Please select a calendar that supports tasks" at the bottom of the panel on my calendar panel.

I see there is discussions for this same situation, but for syncing Google accounts.

Does anyone know if I can do this in Thunderbird or do I just live with events working?

TIA.

For no apparent reason the calendar display has been filled with multiple columns of light and dark blue, side by side and extending top to bottom. This pattern starts in The August 31st column and continues up to and including September 7th. After that the display goes back to normal. Does anyone know why this has happened and how to fix it? Thank you.

Have used Thunderbird for years and never had this issue before. Just upgraded to Thunderbird 115.18.0 esr and my calendar is now blank. Did the upgrade erase the data or is a pointer off somewhere? Can I get my calendar back?

I want to copy my calendar from my Mac whrwe I use Week Calendar into Thunderbird Calendar, but I have not got it to work there. I read somewhere that Thunderbird art developing the calendar. Will it work now??

I successfully linked / synced the thunderbird calendar with the iCloud calendar. Calendar entries manually entered in iCloud or iPhone calendar are successfully synced and are visible in the thunderbird mail. The other way round, syncing the existing entries in the Thunderbird calendar does not work. They do not appear in the iCloud or iPhone calendar. Searching the internet, the specific Thunderbird or Apple help-sites did not provide an obvious solution for this problem. I went through all (or nearly all) recommendations given by Apple, no success to sync from Thunderbird to iCloud.

Any suggestion what to modify or adjust

I have upgraded to TB153.0.3ESR. I've been on the ESR stream for a long time now. But recently, I started having trouble with my google calendar appearing. I've deleted the provider plugin, I've moved to OAuth2, and for the most part, calendars that I have that are read-only from google show up all the time. But my personal read/write google calendar will not show up.

If I go in and delete the cache.sqlite file, and then start Thunderbird, my entries show up. However, if I switch to a different week, my read-only calendars still show up, but my personal calendar goes away.

I've tried everything listed in all of the steps to fix this, but I can't find anything that gives a clue as to what is happening. Anyone else see this?

Steve.

Little thing. None of the sections seemed appropriate. Win 11 153.0.3 (64-bit) In the left-hand panel of Calendar the top left icon of the actual calendar day/week/month matrix is supposed to take you to today (though it's not obvious by the icon which changed a few versions back). When first coming to it after a restart (hibernation mostly in my case) it doesn't move the highlighted day. I have to click first on any other day, then click the icon for it to go to today.
