Thunderbird-Hilfeforum

Thunderbird on my top of the range Win11 laptop was working perfectly until it self-updated to 115.10.1 a couple of days ago. Accessing messages already in the various folder is fast as usual. Unfortunately anything like deleting, downloading a new message is excruciatingly slow : several seconds to click and delete in the inbox. Several seconds to access a message just downloaded. The first time it happened I had a whole bunch of messages deleted because the I kept clicking when I saw no action. It seems to me like it has problem updating the messages in the inbox. Very painful for something that was working so well.

I can't use Thunderbird any more. I open an email and I get 7 copies up across the top of the screen. Delete does not get rid of them, and I am up to over 50 at this point. Please contact me directly at [removed phone# from public support forum] when you have fixed this. For reasons I have just outlined, email is not a good way to communicate.

I assume that everyone else is experiencing this disaster.

I changed back to Thunderbird from Windows Mail. When I did Thunderbird picked up my old emails from 2018 and before. How can I get them out of Inbox and Sent Box ? TU.

I am still receiving regular emails from other sources. But for some reason with this particular email or group of emails, they are unable to send to me anymore. I have no idea why. I have attached the message that my client received when they attempted to send.

How do I go about fixing error message regarding Incoming Mail: UID Fetching Failed

I tried support page, but all threads archived. Not sure how to proceed? Be kind too as I'm also pretty old!

I see that there are 9 messages...Tried tools, checked account settings and couldn't find anything.

Your help would be greatly appreciated. Bad day. My sink is stopped up too!

Hello! I am facing the issue with time zone translations. Here is what I do. First, I create event on web-interface of the google calendar. That account is linked to TB's calendar. This calendar has settings for my timezone as in the first screenshot, that is GMT+3 for Kyiv, Ukraine. It is actually GMT+2 + daylight saving hour in effect. Country is also set to Ukraine. Next, my Windows 11 system is set to set time and timezone automatically, region - Ukraine. It displays UTC+2 Helsinki, Kyiv,... I guess it's Windows settings display quirk, because time is correct and WSL console shows

My TB's calendar is set to have system's timezone as in 3rd screenshot.

Now if I see my event in TB calendar, it is placed one hour later, say 9 am event starts at 10. So reminders also come hour later. Also strange thing is that event properties in TB show correct time like 9:00 till 10:40, but for some strange timezone Europe/Zaporozhye, as in 4th picture.

However, if I set TB's calendar manually to Europe/Kiev (which should be Kyiv, but that's another story), then events are shifted hour up to their right place, 9 am. So this is my issue: when I set calendar forcibly to Kyiv timezone, it does translate it right. When I ask calendar to rely on system's timezone, which indeed is also Kyiv, then I get one hour behind.

I used to read my MSN email via Thunderbird. Then one day it told me I had to provide the MSN password to connect. I discovered that I couldn't connect to MSN at all. Had to create a new password for Microsoft, and I know what that is but then they have you do a second thing for the MSN email, and I connect to that but can't see what the password is. How do I find my MSN email password so I can give it to Thunderbird? I've tried various methods, but no luck. Thanks for any help you can provide.

I want to change the reminder sound. I already downloaded a MP3 file and I selected it on "Reminders", "Use the following sound file". I can see the window that pops up, but no sound is played. Also when I click on Play, it doesn't work. I know the sound file is fine, thus I can play it on my laptop. What should I do? Another question, is there any Add-on with Reminder sounds?

Thanks in advance.

Why is it impossible for Thunderbird to have an option to display the real senders email address instead of just the "fake" display and return address?

I use an addon to add the true address column in version 102, but as usual Mozilla upates disable useful security related updates.

When is Thunderbird going to show this essential true address instead of spending so much time changing the look and feel?

I am stuck with version 102 or another email client until this changes.

Deleting messages is slow to act. So much so that hitting delete for a msg won't activate but when hit again it takes the msg to be deleted and the one that follows. What the...?

My Thunderbird has been working properly for about 30 years, but now refuses to open. Message received says 'Authentication failed'. This happens repeatedly (for at least 20-30 times) and appears to relate to my password. It suggests 'Retry' or 'Enter new password'. The 'Retry' repeats as before so I check the Saved Passwords and enter the one saved. I get the same message. I am using Version 115 and have been for some time.

Could this be related to a change of Profile? There must be a way to reset the password? I have checked all the settings and no errors appear, all settings confirmed.

I have thought about a Recovery Mode and seem to remember seeing a message that I do have that. I just don't know how to access it.

I am having difficulty getting certain emails. I am told by the sender that they "bounce back as a spam warning" Sometimes I don't know the emails I am NOT getting until I'm told. Two my daughter tried sending me an email and it took over 24 hours to get and she was getting bounce back messages. I can't get "NextDoor" notifications, a store in London couldn't email me, a local contractor couldn't send me an email, etc.. It's random who can't email me, but it's becoming increasingly concerning. It's only certain, legitimate emails. I still get all the spam! Where should I begin? I'm on Windows 10 Pro, using a yahoo/att email through Thunderbird. thanks for any suggestions! Cindy

I've been using Thunderbird for years and have never had this problem. Since the upgrade today, after I run Thunderbird once and close it I can no longer start it up again. I have to reboot or use Task Manager to kill it in order to run it. This is on Windows 11. Please help - not an acceptable workaround for long. Optionally, how do I downgrade to previous version? I should know better than allow automatic upgrades.

Adding a couple images below, when it has started successfully it shows as one of the Apps in Task Manager. When I close it, Thunderbird drops into the Background Processes but doesn't end. I have to kill it here in order to start it again.

Clocks went back one hour in Santiago, Chile last week and Thunderbird does not recognise the new time, although Windows (10) does.

The calendar line show the current time to be one hour ahead of the time on Windows; i.e., the Windows time has updated correctly, but the calendar time has not. Adding non-local events to the calendar causes them to be displayed one hour ahead of the correct time.

Changing the calendar setting to use the system timezone, or use America/Santiago has no effect that I can see.

Typing Date() in the error console of Thunderbird gives the correct time, as per Windows.

This also happened in the last time change here in Chile.

How can I fix the Calendar to see the same time as Thunderbird and Windows?
