When I create an event in the Thunderbird calendar and enter text in the “Details” field, the text appears the same color as the black background, making it unreadable, as shown in the attached image. However, red and blue text displays normally. It seems there is no option to specify font colors in the calendar. I would appreciate it if you could suggest a solution. Thank you in advance.

I hate when I receive an email with a calendar event attached. This event automatically imports into my Calendar. I dislike this. Now I am getting spam emails with calendar events attached that are importing into my calendar. With so many calendar events it's not obvious I have junk events.

How do I prevent Thunderbird from automatically importing calendar events. I mean, Thunderbird has no clue whether the event is wanted or not. In fact, when I delete an event automatically imported without my permission, an email is sent out saying I declined the event. This is just not reasonable.

Can I turn off this automation because it caused way more trouble than it's worth?

Thunderbird is difficult to maintain consistent operation.

Periodically, the font color changes without warning, and your settings options is very limited and or 'WELL' hidden.

Making it virtually impossible to find out how to change various screen graphical settings, such as 'font color' or 'font size', etc.

This is not the first time my font color has changed, and I can't find out how to reset the font color in the Calendar editor for any particular calendar event, either creating and or editing a change to the calendar event.

So please, provide me with an instruction on how to change the font color in ANY calendar event, via your Calendar editor.

My Calendar editor in the comments block is set currently with a black background and 'black' font color. So I cannot read a darn thing in the comments block. FYI, when currently using the mail editor, I have a white background with black text, working OK. But NOT the calendar editor.

After all these years, you would of thought Mozilla, either Firefox or Tbird, would have provided a good help dialogue on screen to inform users on how to do things like this. You either have done so and kept it a trade secret, and or have NOT improved upon your terrible user guide instructions.

Thanks in advance.

Hi, I have Thunderbird installed and have been using it to do my email on a self hosted server and to connect to a google calendar account. This has been working for years, but now I'm finding when I accept a meeting invitation via email, its not being put through to the Google Calendar. I've reset the google calendar link a few time (deleted and created again from scratch). Its using the caldav interface to Google calendar. I'm also seeing this random message pop up (see uploaded image) - but there is no details on what to do. Anybody have any clues?

Evidently Thunderbird updated to 157.0.1 (64-bit) on October 1. If I select a reminder, from the list of reminders in the reminder screen, I will get the attached screenshot. I use to get a screen where I could delete the reminder. This screen has three dots. If I click on that there is an option to delete, but it does not work. The best I can do is delete it from the calendar.

I use to get the screenshot that shows selecting the event in the calendar.

Why does the "Delete" not work when I select the event from the reminder screen?

Was this a mistake, am I doing something wrong, or is this a new feature?

Hi currently on version 153.3.1esr 64 bit

Bug

Refer to uploaded images for reference.

When creating a "New Event" I select "No reminder" save and close but reminder is still active and icon appears in the calendar next to the event.

I have to then edit the event and change the setting which has somehow changed from my selected choice of no reminder to custom.

Sorry - first post here - hopefully I followed protocol.

Hi, Why can't I see or find the calendar in Thunderbird anymore? Is it no longer appearing next to "New Message" like it always did? I have a lot of recurring events on it from the many years I've been using it, and I need to add more events. Please advise. Thanks

Getting an error message when i get a notification of an event...ie: birthday coming up... when i click on dismiss. I get this error message:

Server Replied with 400

If you’re seeing this message after snoozing or dismissing a reminder and this is for a calendar you do not want to add or edit events for, you can mark this calendar as read-only to avoid such experience in future. To do so, get to the calendar properties by right-clicking on this calendar in the list in the calendar or task view.

 I follow direction and make my calendar read only but it does not fix the problem.  I continue to receive the error message.
 Anyone have any ideas how to fix?

Thanks

I am setting up an I select "Invite Participants" the pop-up screen locks up.

I have tried to change accounts one at the time with no luck. I also selected the "Attendees" tab near the bottom of the pop-up. That did not help either.

This is running on a Windows 11 Home operating system.

Any help would be appreciated.

PS - I moved from Microsoft Outlook to Thunderbird as I did not like the new Outlook. This has been very frustrating.

WHEN I ENTER AN ITEM IN THE TB CALENDAR IT OFTEN (NOT ALWAYS) SHOWS UP ON MY I PHONE CALENDAR. HOWEVER WHEN ENTER SOMETHING ON THE I PHONE IT NEVER SHOWS UP ON TB

Hello. I regularly sign up for online conferences, then when I get the confirmation email with the details I can't transfer it to the calendar. I even tried saving the ical event separately but when I try opening it using Thunderbird I get an error message. The only way I found is to transfer the contents manually and create an event on calendar, which is time consuming. Anyone knows how to fix this? Thank you in advance

When I create an event, I choose No Reminder. When the event comes dur, I get a reminder. When I edit the event it ha a 'Custom Reminder'. I can't find where to turn this off.

I've asked this before to no response. I JUST did a new search and found a users solution that I just tried to no avail. Which was to add the Provider for Google Calendar Extension, then unsubscribe and resubscribe to my Calendars! The old W7 version of the Calendar had the ability to have a Reminder EMAILED to oneself! That option with the new W11 version has disappeared! Can someone please ask the Coders to re include this option! THANK YOU! I 'LIVE" by this option! My Iphone 3rd party Calendar thankfully still has this option! But I would LOVE to have this back on my W11 Laptop in the Thunderbird Calendar!

Hey, I'd like to switch from Outlook to Thunderbird. I’ve already tried switching to Thunderbird once when I switched to Linux, but—now to my question: The most important feature for me is being able to use different colors in the calendar to mark appointments. I wasn’t able to get this to work on Linux, even with AI. Isn’t this option available? But if people are switching away from Outlook, surely a small feature like this shouldn’t be a problem?

Can anyone help me with this?

My old Win 11 laptop died. So, since I had an SDD adapter, I removed SDD drive from the old laptop and connected it to my new laptop.

- I had already set Thunderbird on the new laptop so I have an existing profile. - I was able, using the Import tool, to get my address book successfully transferred from the old profile. - And while the old calendar name appears in calendar pane, I don't see any of my appointments. - I tried create placeholder calendar, then deleting all the other calendars and retried but still no luck.

I don't want to just copy and paste all the contents from old profile into the new profile as I don't need my old emails or email account data. So, what should I do? Thanks for any help in advance
