Thunderbird Community Forum

I see others are having this same issue with no resolution in sight.

The company I work at is unable to print anything through the print preview in Thunderbird. The current work around is to download, open, then print the file.

Does anyone have any further information on this subject besides going through separate avenues to fix the problem?

Thanks!

About 6 months ago T-bird stopped sending outgoing messages. Each time I typed even a test message to send to myself, it rejected. Everything else works. I have defaulted to my Comcast email client which is not as friendly as T-bird. T-bird is up to date and none of my settings for outgoing mail was changed. Why won't my mail all of the sudden not process? What do I need to do? Thanks in advance.

Message I get when mail is sent below:

Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: resomta-a2p-647141.sys.comcast.net resomta-a2p-647141.sys.comcast.net ESMTP server not available (396356/151.247.189.217).

I want to configure an automatic response to emails that have been forwarded to me from a particular address. I have created a template for the response and it is saved in the Templates folder. I then attempted to create a Filter Rule to send the response. I believe there should be a Reply with Template option in the Perform these action pull-down, but there isn't. I've attached a screen shot to illustrate this.

I'm using Thunderbird 154.0 and Windows 11. Is there a new way of achieving my objective?

I had to recently change my password on my shaw email account. Now thunderbird won't download my emails. I changed the password in the account settings to match the shaw email account password but I keep getting an error message: "Host contacted, sending login information..." and then after a long delay the error message reads "Login to server pop.shaw.ca with username ... failed". Any idea what I'm doing wrong by simply changing the password? I think this happened before and some wonderful human on this forum told me I had to put something before the password or click/unclick a particular box, but I can't find that old answer to my previous question. Thanks in advance for any help someone can offer!

Back when W110 went to w11 I got a new computer and was given great directions here to back up my TB profile by searching %appdata% and copy the thunderbird folder to external source. That file is 198 MB. I do this every month now ..It is my understanding it saves my profile and all emails including local ones. Now in Aug 2026 when i copy this file, I am getting an error a file is too long and have no choice but to skip that file..I will attach a pic of the error. Is this back up ok to use or is it corrupt because of the error?

I also found in TB help there is an export feature in TB to a zip file but that .zip is huge..I did one just in case. I think you just open TB>select hamburger menu three lines on top right>tools>export. I did that back up/export also today and that is a .zip file folder that is less properties like 175 MB.

So now which way is the correct way to keep a safe copy of my TB in case my computer crashes or i have to put on another pc?

I have forgotten my password and even my username in Thunderbird mail. When I try to get a new password, they send it by email. Since I cannot get into email I do not get the code. I want to completely remove my account from the server so I can start fresh. This takes me to username and email + password. I enter the new details and the server having not deleted my account sends, "Incorrect email or password. This is why I want to delete it completely so I can really start a fresh setup. I am using Ubuntu 2404.

Thank you for your help.

I recently (unwisely) refreshed my Windows 10. I had to relaod Thunderbird, but when I tried to reinstal my previous profile, I couldn't do so. I've tried using profile manager. but it only seems to recognise two of the six or so profiles that exist in my profile folder. This means I can't access several years' worth of emails - I need to access these for invoice and work purposes. What is really frustrating is that I can see the profile I need in the profile folder, and all the emails seem to in the Mail/popmail/Inbox folder (all with a much smaller MSF. file of the same name). I've tried importing the profile into Thunderbird, but that doesn't work, it just imports the mailbox with no subfolders. A responder called David has already kindly provided advice (many thanks, David), but unfortunately the solutions haven't worked. Can anybody help?

WHEN I ENTER AN ITEM IN THE TB CALENDAR IT OFTEN (NOT ALWAYS) SHOWS UP ON MY I PHONE CALENDAR. HOWEVER WHEN ENTER SOMETHING ON THE I PHONE IT NEVER SHOWS UP ON TB

Thunderbird not connecting to server. It says timds out and an error occurred connecting to mobile.charter.net. I can neither send or receive emails. This started 8/20/2026

After moving the data file to a new windows 11 machine, the Password Vault no longer remembers passwords. How do I fix? Online searches have told me to delete several files in the Profile folder. I have done this several times w/o success. What are my options other than to find another email client? Thanks, Hank

I don't know where to start. Ever since the update to version 154 I've been having one problem after another: switch from Comcast to Yahoo causes problems with THunderbird, slow indexing, arbitrary folders showing up in different email addresses (confuses my account with my wife's' some of that may be problems dealing with gmail issues), lost email folders after attempted repairs. Three months ago there were none of these problems. I have not yet tried switching back to the last updated version of 153, but 154 does seem to have many more problems. I've run troubleshooting.

I am not a computer expert and there is only so much time I can devote to this, but even computer repair services I've called are at a loss and very pessimistic about the ability to repair things. In all the years (over a decade) my wife and I have used Thunderbird, there have never been as many problems as have surfaced in the last two months. Maybe the best that can be done is to hope that updated versions will gradually fix these issues. I will say that my Macbook Air (M2 chip) has far more problems than my iMac (M1 chip). I have checked and rechecked all server settings (smtp and imap). Although more cumbersome, things perhaps work better if I just stick to webmail options.

I updated to TB154 recently and find that connection to my Outlook calendar via Owl no longer works. In past updates I have been able to turn Owl off and then on again, sign in to Outlook and all is good. This time I was told that I had to unsubscribe from the calendar and then re-subscribe. Unfortunately, nothing that I am trying (sharing, publishing & etc.) is working. I remember that the properties window showed the calendar location as owl:// but everything that I have tried to add after this doesn't work either. Thanks for your assistance.

Добрый день.

При пересылке полученного письма с вложениями от абонента (у абонента почтовый клиент от компании 1С) вложения исчезают. Выяснили, что когда письмо отправляется из 1С "Content-Type: multipart/mixed" , Thunderbird не распознает данный параметр и поэтому удаляет вложения.

Подскажите, какие настройки сделать в почтовом клиенте, чтобы вложения не пропадали?

С уважением, Дмитрий

Dzień dobry, Zgłaszam powtarzający się błąd w programie Thunderbird. Mam problem z drukowaniem załączników w formacie PDF bezpośrednio z okna wiadomości e-mail. Opis problemu: Podczas próby wydruku załącznika PDF, w oknie podglądu pojawia się czarny ekran z komunikatem, że aplikacja nie obsługuje podglądu. Po kliknięciu „Drukuj”, drukarka wypuszcza całkowicie puste, białe kartki. Środowisko: System operacyjny: Windows 11 Drukarka: Canon MF450 Series UFR II Ważne informacje: Drukarka jest w 100% sprawna. Drukowanie tych samych plików PDF po zapisaniu ich na dysku (przez przeglądarkę, Adobe Acrobat) działa bez najmniejszego problemu. Problem występuje wyłącznie wewnątrz Thunderbirda. Co już próbowałam zrobić (bez skutku): Uruchomienie programu w trybie rozwiązywania problemów (Safe Mode). Czyszczenie pamięci podręcznej (cache). Resetowanie ustawień profilu drukarki w Edytorze ustawień (usunięcie parametrów print_printer). Wymuszenie systemowego okna dialogowego przez zmianę print.prefer_system_dialog na true. Wyłączenie zaawansowanych funkcji drukowania w sterowniku Windows i zmiana trybu na rastrowy. Wygląda na to, że wbudowany silnik czytnika PDF w Thunderbirdzie przestał poprawnie komunikować się ze sterownikiem Canon UFR II. Będę wdzięczna za zbadanie tego błędu i pomoc, ponieważ drukowanie bezpośrednio z programu jest mi niezbędne do codziennej pracy. Z poważaniem, Alina

Guten Tag

Das E-Mail-Programm meldet immer „Passwort falsch“ oder GMX verweigert den Zugang? Komisch ist nur, dass es nur mit ihrem E-Mail-Programm so ist. Das Programm bekommt keinen Zugang, obwohl das Passwort ok ist. Alle Programme funktionieren, nur Ihres nicht. Auch eine Neuinstallation hat nicht geholfen. Seit heute kann ich keine E-Mail bei allen Konten mehr abrufen, da bei allen Konten die Passwörter falsch sein sollen?

My filters are broken in Thunderbird. I have deleted and recreated some to no avail.

I moved some folders from Local to under my inbox and it said it would update the filters automatically, but noticed it didn't do this. Looking at the Filter Rules it just left either the first or second column of Perform these actions under the Filter Rules empty rather than updating them. I tried moving the folders back to see if the filters would then work, but it's a mixed bag. Some filter properly and others only go under say Newsletters, but don't filter into Newsletters > Adobe for example. Others just sit in the inbox. I've tried moving some rules to the top of the list hoping that'd give them priority to be run first, but it hasn't helped. I have a lot of filters setup to help me track newsletters, classes, meetings, job applications, etc. I've missed some responses for a couple of days because of this. Any suggestions?

So I don't miss anyone, thanks in advance.
