Thunderbird Version 140.7.1esr, Build ID 20260123195141 User Agent Mozilla/5.0 (X11; Linux x86_64; rv:140.0) Gecko/20100101 OS Linux 6.1.0-33-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.133-1 (2025-04-10) OS Theme Xfce / Adwaita Application Binary /usr/lib/thunderbird/thunderbird-bin

Having a problem with an ATT POP account. TB stopped getting mail. After a minute and a half or so (wish it would time-out faster), I get a pop-up box in the top right of the screen that states: "Connection to server inbound.att.net timed out" and then quickly goes away.

Deleted passwords and cannot see where to create them again, as it never prompts me for new ones.

Thanks.

As the image attachment shows, the 2024 Local Folders item has a different icon and is not in order with the other years. I'm running 147.0.1 on a Windows 11 system. Selecting Reset Folder Order had no effect. Is there a way to better integrate the 2024 local folder with the other years?

The Inbox on my Thunderbird emails shows 224 messages but do not open. I have tried opening and deleting but to no avail.

IMPORTANTLY I am still receiving new emails.

I tutor a number of students in math which necessitates using Greek letters. Easy enough in WordPerfect etc but I can find no usable info on how to do it in Thunderbird.

1. Was able to receive emails sent to my address xxxxxx@xxxxxxx.free-online.co.uk, but unable to SEND my replies. Was getting this notification: 'Send message error. Sending of message failed. An error occurred while sending mail. The mail server responded: Unknown sender. Please verify that your email address is correct in your account settings and try again, OK' (see attached). 2. Checked all settings, all correct as used to be before the problem started. 3. At some stage, I tried changing the password in Settings > Privacy & Security > Passwords > Saved passwords > Saved logins to see if that helped. It didn't. 4. I removed the free-online Server from the Saved logins (Provider: smtp://relay.free-online.net, User: xxxxxxx) with the intention of restoring it with a new password - but found I couldn't restore the free-online server. So I decided the best thing to do was to restore the password as it was before and to ask for help here. >>> That line has now been restored.

NB1. Free-online is a sub section of Plusnet. NB2. Last year I received an email from Greenby saying something about maybe taking over from Plusnet and that I would be notified if and when I had to do anything. I have not received any such instructions so left things as they were. Many thanks for your help from a not-very-techy so stressed old lady.

Re: Thunderbird

I have logged in on my mobile and a secondary laptop - however the folders on the primary device are not reflected; how can I get them to sync?

Thank you

I want to move my TB data store to a different drive but am unsure whether just to move the profile folder or all the other stuff like installs.ini as well. I have changed the datastore entry in settings, but do I need to modify the profiles.ini file as well, and if so what should it be changed to? At present it is in c:\users\mike\app data\roaming\thunderbird and I want it to go to D:\mail profiles. I'd be grateful for advice please. Thanks Mike Phillips

There are emails after the blanks and I am not sure if any are missing. Also some blank email have been marked as favorite. Even after setting the body display to plain text it is blank. And the metadata containt

Hello! It seems Thunderbird emails are suddenly being 'threaded'. It is causing great confusion in my office.

I need to see each email from a person separately in order to find them easily and also to reply to each one at the time it is received.

Can someone please explain in very simple non-techy jargon:- a) How I 'unthread' messages already threaded AND b) How I stop any new ones being threaded in the first place.

Thank you Tylex

I now have 2 accounts in Thunderbird: Local (which has years of folders, but stopped receiving email from my Web mail provider) and my webmail Provider that does not download it from the provider. He claimed it is more modern and safer to synchronize across all devices and keep stuff on the web Mail application. I prefer to keep all my folders and emails on my local computer. Should I use POP? iMAP? to do that? Thanks for your assistance?'

I had previously logged into my Yahoo Mail account. Still, now that I've deleted it, I'm having trouble logging in again. I don't have any extensions installed on Thunderbird, and I can't find any ad blockers or JavaScript settings. I've also cleared all Yahoo cookies from Thunderbird. Does anyone have any suggestions to help resolve this issue?

Changed my BT mail password. I can receive mail but when trying to send I am asked to enter password which is not recognised. The SMTP server does not reccognise this. I have checked other questions and all seems well in my settings, i.e. changed stored passwords, but I must have missed something.Any advice most welcome Don

bold textI recently had my computer get stuck in the "automatic repair" loop making it impossible to boot up. I restored a several months old back up onto a different hard drive. I can boot on the new hard drive, but Thunderbird is missing several months of e-mails. I have tried importing from the old hard disk, but IT DOES NOT WORK. Alll it does is create a new "Local Folders" with nothing in it. I have tried exporting the old profile to a zip file, but it is 14 GB, more than Thunderbird can handle. How can I import the old e-mails into the working version of Thunderbird on the new hard drive. Please, do not say "use the import function" as i have already found it does not work.

Hallo, ich habe seit 2 Wochen Probleme mit der Authentifizierung meines Mailaccounds von AOL. Alles was ich Versuche funktioniert nicht. Ich bekomme jedesmal im eingeblendeten AOL Autentifizierungs Fenster die Meldung "etwas ist schiefgelaufen. Ich habe in meinem AOL Account schon mehrerer Male ein App Passwort für Thunderbird erstellt. Habe dieses App Passwort Thunderbird genannt. Konto ist ein SMTP IMAP Konto, die Ports stimmen auch. Ich habe mein AOL Mailkonto mittlerweile in Thunderbird komplett gelöscht und ebenfalls die AOL Passwörter gelöscht. Die Authentifizierungsmethode für outh2 ist angewählt und Cookies sind eingeschaltet.

Ich kann machen was ich will. Die Autentifizierung funktioniert nicht.

Woran kann das noch liegen. Ich bin mittlerweile ratlos.

Hi,

Since updating to Thunderbird 140.7.1esr (64-bit) on Windows 11, moving messages from Inbox to any folder takes about 7 seconds.

Details:

Account type: IMAP (Cogeco)

Happens in all folders

Inbox has ~600 messages (not large)

Was working normally before the recent update

Delay occurs every time moving a message from Inbox to another folder

No freezing — just a delay before the move completes

No antivirus changes

Issue started immediately after update

This appears to be related to IMAP sync behavior introduced in 140.x.

Has anyone else reported this, or is there a known regression?

Thank you.
