Using Thunderbird 128.5.0esr (64-bit) on 128.5.0esr (64-bit). In calendar view, I see all my appointments with the background colour of the calendar they are in (see attached). In my inbox view, I have the Events tab open at the right. All day events have the background colour of the appropriate calendar, but ones with timings have a dot. (see attached). How do I make ALL calendar events have the background colour of the associated calendar in the mail events tab??

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.

Hi. Ubuntu Unity 24.04 Thunderbird 140.5

When creating a New Message, the top 5 lines are missing - i.e the “End: (U)” (end time) line is displayed at the top of the screen. The only way to enter the Title of the Event is to drag the window down. Also, the Event window CANNOT be resized. This has been happening for more than a year now. Can you help? Thanks, M...

if I type a hyperlink into the Calendar description field it does not link to the url.

The mouse pointer does not change from a cursor to a pointy hand when I hover over it

I have also tried using the 'Link' button and that creates a blue/underlined url like a traditional clickable link but the result is the same as before.

Please help troubleshoot the problem, at the moment I'm having to copy and paste every link which becomes tedious when there are lots of links

Thanks

Hello I searched the help articles and was surprised I could not find anything on this. I receive different calendar entry files, in this case a .VCS calendar file, from services I use to use as a calendar entry i.e. a reservation or other. I am able to import this file and create the calendar item in Google Calendar, however if I am on Thunderbird Calendar, I have been unable to discover a way to import. Am I missing this function? What are the steps needed to import a VCS file into Thunderbird Calendar? Thanks Mozilla community! -kozy

Hi everyone.

Hoping someone may be able to help. I see that other users are able to fully highlight the events in calendar. I seem to be only able to highlight 2/3's (see image)

Thanks in advance

Hi, my Thunderbird calendar reminders are coming up 4 hours after the meeting.

Running Kubuntu. System locale/timezone OK, TBird set to use system time (though manually making it the same didn't help). HW Clock matches system time. Pacific/Auckland.

Tried exporting all my appointments and re-importing them - no change.

Hello, Yesterday the Google calendar tab opened with a message and stupidly I didn't read it - I just closed the tab and thought I'd check it later. Then I realised I could neither dismiss TB calendar notifications or snooze them. Next I realised I could no longer add to the TB calendar or delete any items that were already in there. I'm not sure if there has been a recent update which may have brought this about but any help would be very much appreciated. Thank you.

I have just had a scam calendar entry added without me accepting the invite or an email requesting it.

The entry has clickable links - obviously scam/spam

How could that happen?

Hello, I probably desactivated by mistake the reminder pop up window for event and tasks in the agenda. So that i do not get any warning 1 day before the event as specified in the creation of the event. How can i re-instate this alarm ? Tks brds

I came into my home office this morning and started my Windows 10 machine from scratch (cold boot). I loaded Thunderbird and read and deleted some email. Then I went to enter a Task in the same calendar I always install Tasks in and it won't let me enter a new Task at all. The input field tells me to select a calendar that supports tasks. Well, I have! I open the Events and Messages menu option and the Enter Task command is grayed out. What the heck is going on? How can I get the ability to enter Tasks back?

I'm getting a little tired of dealing with all the issues in Thunderbird. I have spent hours trying to debug this with no success.

Hi,

Since upgrading to thunderbird 128.6.0esr, my shared google calendars no longer show any events.

The activity manager shows it is stuck trying to sync, but not going anywhere.

Onn checking the developer logs, the following messages are displayed.

Anybody else having this problem or know of a solution. (I have removed "CALDAV" and "TB SYNC" extensions - also installed "TB SYNC 4")

Thanks Paul

I am trying to create a personal calendar as a checklist for chores. Is it possible to make a list of tasks without adding a time to each task? When I try to print the calendar, the time stamp takes a lot of space and is unnecessary for my purposes. Also, I have added birthdays/anniversaries/holidays to my calendar, and these also require an unnecessary time stamp. Is there a way to add these without an associated time?

I use TB as a personal home email client & calendar. All the prenamed Category labels for events are primarily oriented to business use. If there a way to rename the Categories and apply a color that I want?

I’m using Thunderbird on a MacBook Air M1 2020 with 103 GB of free disk space and 8 GB memory. I’m using it primarily as a calendar and task management system because I like the reminder options in Thunderbird. I use local calendars. Thunderbird auto-updated to V 128.5.2 from V115.18.0 on 12/17/24 (I didn’t realize auto-update was set) and since then gets hung every time a reminder comes up and I either dismiss it or snooze it. I have to Force Quit Thunderbird to get the spinning beach ball to go away. I backup my computer weekly using Time Machine and tried restoring to 115.8.0, but was unable to restore my profile with my current calendar items on it. I got an error message saying that the new version of my profile (with my local calendars) is incompatible with Thunderbird V 115.8.0. Is there any way to get my current calendar info into an older version of Thunderbird, or better yet, create a fix so that it doesn’t get hung? If it's time for me to move to a different application for this use, just be honest. Thanks in advance for your advice and expertise!
