My first support request about this was posted on Mon, Nov 18 (8:53 a.m.). I never got a response--probably my fault for posting a minor correction which may have caused everyone else to think someone knowledgeable had responded. I apologize for starting a new thread, but it’s been almost a week now and I really need help. The situation: I get my email via POP, and something got corrupted as a result of doing a backup of TB on Nov 15 using MozBackup. Following advice by Toad-Hall on 11/7/23 to a similar support request, in Troubleshooting Information, inside Profile folder, then in Mail, then in the folder for my server, I renamed “Inbox” as “OldInbox.” A new Inbox and new Inbox.msf got created in Mail > 'my-server.' The new Inbox is 0 KB and is dated to the Nov 14, the evening before I did the MozBackup. The date on the new Inbox.msf keeps advancing. There’s a OldInbox.msf file too, with date that keeps advancing. The new Inbox.msf file doesn’t work or isn’t getting used or some such. When I open TB, Inbox still shows the same old list of emails (now inaccessible) that used to be there and that are now accessible in the folder OldInbox. I still get the error message when I try to Get Messages. TB is still not downloading emails from the mail server. How do I get a functioning Inbox?

Addendum Monday, Nov 25, 8:56: I *think* some of the problem has to do with a mixup bwtween two different profiles (mine and an old one for my husband). After my post last evening, I deleted his profile, and lost much of *my* stuff. So I then restored TB from the Nov 15 backup, using MozBackup, and am now pretty much back to where I was at the time of the post above.

We have Thunderbird on 4 computers. We all have our own personal account and then we share one account. Emails for the shared account do not appear on all the computers consistently. It varies by the day. The account is an IMAP account. On both the shared account and the personal account e-mails randomly disappear. This all started within the last few months. All was well until then. NO changes to the computers. HELP!

I use apple ipads and fons. one of the ipads is updated to 18.01 and the other is older. The newer updated ipad has suddenly stopped receiving emails. My server is HostEurope. who can I turn to for help. Thanks alot!!!

I've tried the new thunderbird mobile. Very good indeed. Just two things missing for me. There is no way to add/delete a new folder. Second there is no way to print an email. Let me know when these points might be included.Thanks

Sehr geehrte Damen und Herren,

ich habe das o.a. Mailprogramm von Tunderbird schon etliche Jahre auf meinem PC. Nachdem ich jetzt durch Urlaub meinen Eingangsspeicher längere Zeit nicht geleert hatte, waren ca. 1000 Mails darin enthalten. Ich habe versucht, alle zu löschen, was nicht gelang. Ich konnte nur die Mails löschen, die auf meinem Eingang ersichtlich waren. Seither ist es mir nicht möglich, weitere E-Mails zu empfangen! Ich kann sehr wohl Mails versenden, aber nicht empfangen. Das gilt für beide Konten, nämlich erwinh@kstp.at und Schweden60@ kstp.at ! Ich habe keine Einstellungen geändert und auch mein Internetanbieter Kabelplus St. Pölten hat keine anderen Einstellungen durchgeführt! Es ist ganz kurz einmal "aufgepoppt", mein Zertifikat ist abgelaufen! Ich weiß nicht welches Zertifikat und wie ich das verlängern könnte, damit die Eingänge auf die Mail-Konten wieder funktionieren? Bitte um ihre Unterstützung! MFG Erwin Heiser

Hallo, ich war 3 Wochen in Urlaub. Danach habe ich auf dem PC normalerweise jede Menge Mails, Spam usw. Jetzt überhaupt keine. Woran liegt das ? Das Einzige, was mir einfällt, daß ich auf meinem Norton Programm eine Aktualisierung von Thunderbird gemacht habe. Ergebnis : meine bisherige Version war 115.16.3 , die neueste Version ebenfalls 115.16.3. Was kann ich tun ? Danke, Wilhelm

ich will meine pers email Sieg1@beasieg.de einrichten, hatte bisher siegenglert@gmx.de diese hat das programm übernommen jetzt kann ich Sieg1@beasieg.de nicht mehr installieren

Thunderbird was working perfectly for Yahoo and another email (and the gmail inbox).

It is still working for for the second account and the gmail inbox!

The last yahoo message received via Thunderbird was at 22 November 2024 at 12.15 pm. I can see from the yahoo account online that I have received several more emails since then.

I tried to send a yahoo email today using Thunderbird;  result "Login to server smtp.mail.yahoo.com ...failed. I haven't changed anything. 

The Yahoo account server settings show: POP mail server pop.mail.yahoo.com port 995 SSL/TLS OAuth2

There's no SMPT server information displayed in settings.

Re the gmail inbox, when I set up thunderbird on my new computer in May and imported the email accounts, everything was present and correct except for the gmail account for which only the inbox and contents arrived.

There's no problem with any of the accounts when I log in online.

Can anyone help me with three questions please:

Is there a problem with Thunderbird 128.4.3esr?

If not how do I get it working again without having to do anything difficult or technical?

How can I recover the other folders from the third email account? I imported the account by copying the Thunderbird roaming profile in exactly the same way as for the other two accounts which arrived intact.

Thank you.

I'm having trouble with Thunderbird on my new Windows11 laptop. I've used Thunderbird for years and years on the old Windows10 one, but can't get it to work right on the new one. The version info it gives is "128.4.4esr (64-bit)"

Specifically two problems. (1) Every time it starts it asks for my yahoo server's password. Even though I check the box asking it to remember it, it doesn't. Under Settings->Privacy&Security (under Passwords)->SavedPasswords, the list is empty. (2) Second problem (may be same as first, but in a different form) Whenever I try to send an email message, it fails. It waits a long long time and then gives a popup saying "Login to server smtp.mail.yahoo.com with username bill.marshall@verizon.net failed." It gives me an option to enter a new password, and if I click there it doesn't let me enter the password again, just re-tries, again waits a long long time, then gives the same error popup. When I cancel, it gives a new popup saying to check the password and verify the 'Authentication method' in Account Settings (which I have done, and all looks OK).

Thanks Bill Marshall, bill.marshall@verizon.net

Running 115.16.3 because I have a Windows 7 Pro computer. Fine for years! Then a series of power failures and system crashes.

Now Thunderbird looks very plain - black and white lines, no 3D blue colors, Delete button is text only, it used to be red. Entire interface looks simple and old.

Checked my outgoing and incoming server settings. They match the settings in Edison+ Email that I use on my phone. Phone is getting new messages, Thunderbird on my desktop is not.

Outgoing mail asks for a password each time, which it did not before. I know the password, but what a pain.

I have hundreds, actually thousands of emails saved in local folders. They are all there, but I am worried if I can migrate them if I move it to a different computer.

My inbox has nearly 300 messages now, and growing rapidly.

HELP!

If there is one thing I have always disliked is 'email migrations. When deciding to switch from Thunderbird to Outlook for the MBOX data of 2024-25, I was expecting to face a really annoying and long process. But surprisingly, it wasn’t. Here’s what happened.

I began by defining tools that would help in the transition to be smooth. Out of trying many options, I found the WebbyAcad MBOX converter software. It appeared to be reviewed and featured well, so I said let me try it.

The general preparation was very simple. The tool was downloaded, and I imported the MBOX files and then chose PST as the file type to save my results. The best part? It was having the ability to batch convert something, which would have taken me hours to do.

As soon as I clicked on “Convert,” I could hardly believe how fast a work of it was. That is an undeniable advantage – every mail, folder, and even attachment was intact. I did not even delete a single file, which was way faster than I anticipated.

That which I had probably estimated to take days, was actually achieved in minutes. These new PST files are quite compatible with Outlook 2024 and I had no problem at all trying to access all my data.

If you find yourself in a similar situation, there is a solution; email migrations don’t have to be a headache. There shouldn’t be any hitches if you get the right tool. In doing what I thought was an impossible mission after research, the WebbyAcad MBOX email migrator made it easy as pie.

Hello, I am planning to do a fresh Linux install and in this context I also want to setup Thunderbird completely new, starting with the default settings. However, there are two things I would like to backup and restore (export and import).

1. The information which emails I have explicitly labelled as "Junk"/"No junk"
2. The information from which domains I allow loading remote content

I think this makes a lot of sense because I can setup my accounts easily and the mails, addresses and calendars will be synced from the cloud, and view configuration is no big deal either. Only that kind of "user data" that was gathered over several years is something I want to hold on to, and be able to continue to use. Is this possible somehow? I am not afraid, e.g., to manually copy individual files from the profile folder, if that data is stored cleanly separated somewhere. Kind regards, Chris

For some reason, I was obliged to change the password on one of my external email box. I made a mistake creating a new mail box in Thunderbird with the same name and the new password, instead of just informing the new password on the existing mail box. I have now two mailboxes with the same name in Thunderbird. One is enough, but I can't find the way to remove / cancel the second one...

Thank you for your help

I've found that some of my emaIls in very latest Thunderbird mail client on Windows 10 have had their content replaced with a phishing email - the title of the email is as per the existing email received yesterday but the content is a phishing email made to look like a contact request from a motor insurance provider that I used years ago and the email is addressed to the email address I used when dealing with said insurance company.  It's only an issue with Thunderbird as the email looks fine on my mobile phone and in Outlook.  Either Thunderbird itself is compromised or one of the installed extensions is compromised.

Has anyone come across a similar issue?

I'm running an antivirus scan but I think I might uninstall and wipe clean Thunderbird if the scan shows no issues.

Hi I've just realised that Thunderbird has been deleting inbox messages from server with IMAP server setting. Is there any way how to turn this off? I would expect this to happen with POP but not with IMAP. Cheers Mike
