Here we go again,I was unable to send email from my yahoo,ca account. I managed to get a password form yahoo and when I re-logged in, all my folders have disappeared. They are still on the webmail version on yahoo.ca, I can now send email though How can I get them back as the folder that the email has: C:\Users\John\AppData\Roaming\Thunderbird\Profiles\a51cb43e.default-release\ImapMail\imap.mail.yahoo-4.com Does not work

I also have Gmail issues for another time

Hi everyone, I’m looking for a reliable method to convert multiple MBOX files to PDF format with attachments preserved. I have several email archives, and manually opening and saving each email as a PDF would take too much time. I also want to retain important email details, such as sender, recipient, subject, date, and attachments.

While searching online for the best MBOX to PDF converter in 2026, I came across Aryson MBOX to PDF Converter Tool. It appears to support bulk conversion and attachment handling. Has anyone here used Aryson for this purpose? How was your experience with the conversion quality, attachment preservation, and overall performance? I’d appreciate genuine feedback or suggestions for other reliable methods

This morning, my email Inbox is empty. I use Thunderbird for four email accounts, and three of them are fine, but the fourth one has an empty Inbox this morning. I didn't (intentionally, anyway) move the emails anywhere, and they do appear to be in the All Mail folder, so I didn't lose them entirely. But I keep my emails mostly in my Inbox and they aren't there anymore.

Any ideas what happened to make them disappear and how I can get them back to the Inbox?

Thanks!

Bonjour,

Je sollicite votre aide concernant la restauration de dossiers de messagerie dans Thunderbird.

Contexte : Le problème est survenu suite à un glisser-déposer par erreur d'un dossier (et ses sous-dossiers) depuis ma boîte nominative (IMAP) vers une boîte mail générique partagée. Le dossier a disparu de l'interface Thunderbird et du Webmail, mais la arborescence physique existe toujours sur mon disque.

Détails techniques :

Dans Paramètres des comptes > Dossiers locaux, le Répertoire local pointe sur : C:\Users\sojanati\messagerie\Mail

Dans ce répertoire, je retrouve la structure sous forme de dossiers .sbd (comme INBOX.sbd) ainsi que des fichiers d'index .msf.

Cependant, les sous-dossiers et leur contenu n'apparaissent pas dans l'interface Thunderbird sous Dossiers locaux.

Comment puis-je forcer Thunderbird à réindexer ces dossiers .sbd ou récupérer les messages associés ?

Merci d'avance pour votre aide !

Hallo, ich habe bisher mein AOL Konto über Thunderbird (Version 153.4.0esr (64-Bit)) auf meinem Windows PC (Win 11) genutzt. Vor ein paar Tagen konnte keine Verbinung mehr zu AOL Server aufgenommen werden und es fand keine synchronisierung mehr statt. Ich habe mein AOL Konto in Thunderbird gelöscht und wollte es neu hinzufügen. Der Dialog zum Hinzufügen eines e-Mail-Kontos startet, ich gebe meine AOL Mailadresse ein, die Standard-E-Mail-Einstellungen werden angezeigt (mit Authorisierung OAuth2), das AOL Anmeldeverfahren wird gestartet, meine AOL Mailadresse ist eingetragen, ich nutze die andere Anmeldemethode (mit Kennwort), gebe mein AOL Passwort ein (das funktioniert, wenn ich mich direkt bei AOL anmelde), der Dialog mit der Überprüfung der Zugangsdaten bzw. die Bestätigung der Zugriffe, ich stimme den AGB zu, aber nun kommt die Fehlermeldung von der Seite (https://api.login.yahoo.com/oauth2/error?client_id=dj0yJmk9MGNoTTQ0SjhIN1dSJmQ9WVdrOVdIVnFkVVp2UkZNbWNHbzlNQT09JnM9Y29uc3VtZXJzZWNyZXQmc3Y9MCZ4PTNm&error=unauthorized_client&error_description=invalid+client+id):

Ein Problem ist aufgetreten Versuchen Sie es erneut, oder senden Sie als Entwickler eine andere Anfrage.

Wo liegt das Problem?

Ich hoffe auf Ihre Hilfe Andreas Zai

Unable to add an attachment to the email being sent. After I create answer, I can't add attachement. No any action after clicking "add attachement", no action after clicking menu "add file (Ctr+Shift+A)". Adding file is possible only by windows menu "Send by e-mail", thunderbird create new e-mail with attachment, I must give e-mail adress and only this way I can sent e-mail with attachment.

I recently lost all of my saved emails and the folders they are in on my laptop computer. They are fine on my desktop computer. I have tried everything to restore them to my laptop computer. (backup option, export profiles, etc) But when I try to restore them to my laptop nothing works and they are not restored to it. I have tried every option that I used to save them but they will not restore. P.S I have tried every option on Google searches with no luck. I am running Windows 11. As a side note I never had a single problem when I was using Windows 10 and Moz Backup still worked. Help Richard Clauser [redacted from public] @gmail.com

I am attempting to add my current email to another computer, it tells me it needs hostname. I enter as I have before but it doesn't recognize. the name is mail.riverbender.com I have setup several email accounts with this hostname, in thunderbird.

When i am filing/deleting of messages into my local folders after a bit the correspondent and the subject get mismatched somehow.

I had a message from Jane Doe regarding bowling (only reason I would hear from her) after I had deleted her messages, her name started showing up as the coorespondent with subjects such as Rush concert information and here is your order information and a lot (approximately 10) messages that have nothing to do with her.

What should I do. Filing and preserving email is very important to me which is why I picked your product. If I could get it to work effectively without these weird glitches I would happily pay for it.

Side note : If I try to highlight messages in bulk and move them manually to a folder it will move folders and messages and make a big mess. The only way I can do it is to right click to get the little box to show up.

Thank you, (PII redacted by moderator)

I like to keep my inbox empty. Generally archive and delete (having dealt with the email) work well. However occasionally it is useful to delay them by a day, a week, a month... Please add this feature. It was in my old email client!

Otherwise I am loving Thunderbird!

When replying to an email, I type the first line of text in the text field and then paragraph (carriage return) using the ENTER key. This causes the first line of text to disappear. This has been happening all day today, several times. Closing and reopening Thunderbird does not solve the problem. Rebooting the device does not solve the problem.

Using Outlook - this morning received the following email: I just clicked on it to copy to send to you and it disappeared. It was a thank you for applying to a job. I did not do so. I am not sure what this is all about. The dark web has my email address?? Appreciate any thoughts. Thanks.

Thunderbird 156 and 157 resassigns deleted folder from Outlook to name Trash.

Because user cannot rename it back to deleted user ends up with 2 Trash folders.

I reported this earlier but never got any fix nor help.

Within the past day or so, which means 7-18-26 or later, some of my email messages on thunderbird for my pc have a "From" description that is not correct. I look at the messages, and the "From" is entirely different than the "From" description when looking at the email message list. I have never encountered this problem before. I'm using thunderbird 152.0.1 64-bit on my pc.
