all INBOX emails disappeared from one of my email accounts. The other is working fine. Emails that were still open in one of the tabs are also now just an empty tab. --no luck repairing folder or deleting INBOX.msf. If I go to the Charter/Spectrum website the emails are still showing What should I try next?

My Thunderbird, from Debian is:

140.13.0esr

I've often wondered what the point of 'extended support release' (I think) really means. It sounds retrograde. Should I switch/upgrade?

When I added a new subfolder it disappeared. When I tried to add it again it just shows up. Today I can't add a new subfolder and the info in the folder I had won't show up.

I just installed Thunderbird 154, but i cannot find the address book. i know it exists as T-bird does preload my addresses when i create a new email. Is there a button that I am not seeing?

Bonjour,

Depuis le passage à Thunderbird 154.0 (64 bits), plusieurs de mes comptes IMAP ont vu leur arborescence se modifier de façon inattendue.

Avant, j’avais une présentation de ce type :

Brouillons Envoyés Archives Indésirables Corbeille Courrier entrant Clients Fournisseurs etc.

Depuis peu, sur plusieurs comptes, les dossiers spéciaux Brouillons, Envoyés, Archives, Indésirables, Corbeille apparaissent désormais sous Courrier entrant.

Le phénomène touche notamment :

un compte Orange ; un compte hébergé sur un domaine personnel ; un autre compte professionnel IMAP.

En revanche, un compte Free reste affiché correctement.

En comparant les abonnements IMAP, je constate que :

sur le compte Free, Sent, Trash, etc. sont réellement à la racine du serveur, tandis que les dossiers personnels sont sous INBOX ; sur les comptes qui posent problème, les dossiers spéciaux et les dossiers personnels sont tous sous INBOX.

J’ai essayé le paramètre :

Paramètres serveur > Avancés > Dossier sur le serveur IMAP = INBOX

Cela fait bien remonter les dossiers spéciaux au niveau du compte, mais cela remonte également tous les dossiers personnels, donc l’arborescence devient entièrement plate.

J’ai également constaté qu’un déplacement manuel peut produire une erreur du serveur du type :

Client tried to access nonexistent namespace. Mailbox name should probably be prefixed with: INBOX.

Je cherche donc à savoir :

Thunderbird 154 a-t-il modifié la façon dont les dossiers spéciaux IMAP (Sent, Drafts, Trash, etc.) sont affichés lorsqu’ils sont physiquement sous INBOX ? Existe-t-il un réglage permettant de conserver les dossiers personnels sous Courrier entrant, tout en affichant les dossiers spéciaux au niveau du compte comme auparavant ? S’agit-il d’un comportement connu ou d’un bug de la version 154 ?

Je peux fournir les paramètres IMAP avancés et les captures des fenêtres S’abonner si nécessaire.

Merci.

I've been using TB for years. Lately I can be browsing the Inbox when the contents will disappear and I get a message saying something like no messages found. After about 30 seconds the Inbox is displayed again.

TB never used to do this and it is similar to Firefox refreshing the screen which it also never used to do this.

Also how do I get from the Beta version to the standard version?

Good morning -PLEASE help - I had numerous e-mails in my inbox that went away - when I opened this am only yesterday's were in there ......I am sooooooooo IT incompetent

Thank you in advance - some very important stuff was in there.....

After the latest update of thunderbird on 19-aug-26 I found that I could send emails but not receive them. After researching the problem I changed my server setting for imap to match what spectrum recommends, confirmed I did it correctly by spectrum. Test imap connection fails, but gives no information as to why. Tried 3 dirrent imap server: 1. imap.charter.ner 2. mobile.charter.net 3. mail.twc.com I confirmed with spectrum that I'm using the correct port number.

Is it possible to rill back thunderbird to the last release? Thanks for any and all help. I've used both google and duck duck go AI to look for answers.

account stopped receiving messages after 140.1.1esr update I deleted the account. I then tried to add a new account. It does not ask for a password but only Name and Email. Response: "Unable to log in at server. Probably wrong configuration, username, or password". Two other workstations use the same account and they are not having any issues with the account.

Even since Thunderbird 141.0 (64-bit) I've had two annoyances. I'm calling them that because it does not stop or prevent me from getting my email, that would be a problem. Here are my two annoyances:

1A. I have a message filter set up to these conditions. Match any of the following From isn't in my address book Personal Address Book From isn't in my address book Collected Address Delete Message

This message filter is for an account that should not be receiving important emails. I wanted all of the junk emails emptied so I would not have to intervene. There are emails coming to this account, but not of great importance nor frequency. Those are in an address book.

1B. This is on my primary account. Match any of the following From contains (I enter email address here) Delete Message

Since I use this account for business/personal use, I filter out spam/junk email this way.

The annoyance is the filters are not deleting the messages as they should and I am having to open the message filter on each account and click on the Run Now, and then it works. It is not 100 percent of the time not doing what it should, but about 65 percent of the time. I've used these two message filters for years and they have always worked. This annoyance only showed up in version 141.0 (64-bit) (+ the ESR Version - see below).

2. My second annoyance is when I click on New Message, then it creates one and I go to Insert then click on Image then Choose File (and pick one) then click Open then the square box appears and I click the OK button. As soon as I click OK, it throws me out of the email/message that I am editing to the main email section before you clicked on New Message. I have to go to the Thunderbird icon on my taskbar then hover over it to see two previews come up, the main email section and the message that I was working on. Then I click the latter.

So there are my two annoyances. If anyone else has experienced this and found a solution, it would be with gratitude if you would share that with me. I will add that I have reinstalled Thunderbird and that made no difference at all. I did have the ESR version and it too had the same annoyances as this version, so it did not help for me to change/install versions.

Thanks!

I have a new PC. I have added five email accounts, three different hosts, with some difficulty. Thunderbird finds the details for others but then refuses with the message Authentication error. Unable to log in at server. Probably wrong configuration, username or password.

I added Thunderbird by copying from my old PC. The hosts for those not yet added are the same as those added.

This is the message I get when it does not go. I contacted Spectrum and they told me to check Thunderbird.

Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: p-impout004.msg.pkvw.co.charter.net cmsmtp 73.238.167.193 blocked. Please see https://www.spectrum.net/support/internet/understanding-email-error-codes for more information. AUP#Out-1130.

I recently migrated to Linux and was able to reinstall my Thunderbird account. However in the previous MS windows version I was able 'choose 'the font as well as other basics for each account signature. In the version I now have it is purely a default font. I tried the forum solution which was to create a message in html then copy it in- didn't work. i don't want to have to add a file everytime when it wasn't necessary before? I want a different signature for 5 different purpose accounts. Why can't I do this in this version of Thunderbird? I also no longer see what font I am in. I just created a dummy email and chose a font. I doubt that will be in place for my next message ie it doesn't offer a default option as outlook would

I have been using Thunderbird on my PC for years and when I got my last PC, I found a article to help me move my files. I am now looking for instructions on how to move my Thunderbird files from the PC to the Mac so I can continue using it as I have been.

Hi,

I'm running the latest version of Thunderbird 140.12.1esr on 15.7.7 (24G720) on an M1 processor.

I'm witnessing Memory leak > Thunderbird who usually use 800MB jumps to Gb up to 60Gb

It makes this version unusable.

Here is a loom of the incident: https://www.loom.com/share/0b8e661b42d64d749d80adfd71fd1e04

+ a screenshot

Anyone can help ?

Best Olivier

Latest version of Windows 11 Thunderbird has stopped displaying the message body in the message pane ( right side of the screen) . I have another email client that displays the message body perfectly. It does display the message body of any messages save in a folder but will not display newly received messages in the pane. When I click on the message sometimes I get a white blank screen in the message body display pane. HELP!

In Thunderbird, I have several email folder names that were changed, and I also created new folders, but I cannot see them after restarting Thunderbird. How do I get these folders back? In the past, I have gone to the server of my email provider and fixed this sort of issue there. This time I have not been as successful. How do I get my missing email folders back?

I have been using Thunderbird successfully for sometime and since yesterday there were no new emails in my inbox. This coincided with Thunderbird being upgraded, so I am told. So, I tested by sending an email to myself but TB kept assuming my old email address was valid (died last year) and any attempt to get in and edit my address failed because it kept thinking the old email was was still valid. So, I installed Betterbird, hoping it might work but it copied over my profile, etc and it had the same problem! I guess I could look far another email client but I want to stay with Thunderbird.

Any suggestions please. Robin

I have successfully added five ntlworld.com email accounts in Thunderbird but my two personal ones keep coming up with Authentication error. Each time the screen shows the details of the account found automatically so the information is coming from somewhere.

Advice I gratefully received was to Disable the account hub in Settings / General, then add the account from New Account, and use an application specific password assigned via your email provider.

Virginmedia no longer seems to acknowledge ntlworld accounts but says they are talktalk. However, talktalk says they do not hold the accounts.

I do not understand how I can disable the account hub in Settings when it has not loaded.

I cannot understand why two of the accounts do not load.
