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 !

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 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.

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.

При регистрации аккаунта в почтовом клиенте выдает постоянную ошибку, ссылая на то, что исходящий сервер уже ссуществует. Почта .com При этом ранее аккаунт был создан и все прекрасно работало.

I received an invite to join thundermail. I began the process of signing up, however I was unable to finish fully activating my account due to losing internet at my apartment. The email says while the invite doesn't expire, the address I chose does, which I presume has already happened, but now when I attempted to go through the process again I get a "WE'RE SORRY" page when I attempt to follow a link from an email that lists: "

Your administrator has just requested that you update your Thunderbird account by performing the following action(s): Verify Email. Click on the link below to start this process."

Not sure exactly how to proceed. More than a bit cumbersome.

Dear T-bird Community Helpers,

This is my 1st use of any Mozilla mutual help community message board. I'm learning the ropes.

Re. the OS build: I never use beta anything. I established the folder, that went zero on me, recently (less than 2 weeks ago). I hadn't yet backed it up onto the cloud or a flash drive or other medium. Was just about to, but thought I'd rename the folder 1st, 9/13.

My mistake there, but not in the renaming. Never renamed a T-bird folder before. I had set up Thunderbird the week before 9/13, as a backup to e-mails in my Earthlink WebMail Premium account. 1st as a POP account, then later that week, after checking with a reputable AI interface, I made an IMAP.

Today I couldn't find any prior messages in this community board. That I, with my best focus, found relevant to my situation.

I try to learn what is involved, first, in decisions between products, accounts, and methods to follow. But I don't have all day. I don't short-shrift research, but I don't have all day. I relied on an AI bot when I had second thoughts on appropriateness of POP account, and it recommended IMAP account be added. Not substituted for the POP one, though---I asked it about that. too.

I work hard to learn computer terms but am not deeply skilled with computer stuff. I cannot generally read between the lines, to infer what sub-step to take to make the next listed step likelier to work. Nor can I understand very unnecessarily complex instructions, so please be feasibly simple in how you instruct me to find a way to restore my local folder. I don't know the exact name it had before. I use spelling tricks to keep folder names short, so there are MANY possibilities for the old name of that folder.

Your advice, please. I will be grateful for friendly, complete, instructions. Worded simply as is feasible. And questions 1st, sure, if you need to know more 1st.

         Thank You,
             AK

Hi, Hoping I can get some help here, I couldn't find an answer in the search topics.

I have lost a few local subfolders. First the subfolders lost the emails contained in them and then the subfolders themselves disappeared.

I renamed the main folder just removing the year from the folder name and not long after that the above happened.

I have tried the following:

• Searching the help topics • Searching the forum • Closing reopening Thunderbird • I removed .msf files and restarted Thunderbird

I am not sure what I can do now.

Thanks in advance for any help.
