I exported Outlook Contacts to a .csv file and imported giberish to the Thunderbird Personal Address book. Can the giberish be block deleted? How should the Outlook Contacts be transferred to Thunderbird? Secondly, I exported Outlook Contacts to gmail and have used them on the web based gmail app to send messages. Don't remeber how the gmail contacts got to the Thunderbird Address book, but they don't work. The first message I sent from Thunderbird from my wife's gmail address to my hotmail address produced the following error:

Sending of the message failed. An error occurred while sending mail. The mail server responded: The recipient address <Steve Thompson (sthompson2486@hotmail.com> is not a valid RFC 5321 address. For more information, go to

specifications. 00721157ae682-70ca8508772sm13401897b3.82 - gsmtp. Please check the message recipient ""Steve Thompson (sthompson2486"@hotmail.com" and try again.

Both imported address books are unuseable. Please help.

Guten Tag, ich arbeite mit Thunderbird auf Linux Mint. Jeweils in den aktuellsten Versionen: Linux Mint 22.1 Cinnamon Thunderbird 128.11.0esr (64-Bit)

Auf meinem bisherigen Rechner begann Thunderbird mit dem letzten Upgrade von Linux Mint langsamer zu laufen. Da ich mir nicht anders zu helfen wusste, habe ich in einen neuen Computer investiert. Obwohl der Rechner jetzt deutlich performanter sein sollte, hängt Thunderbird mindestens genauso wie vorher. Zum Teil ruft Thunderbird auf dem neuen Rechner auch keine neuen E-Mails mehr ab. Ein Neustart korrigiert das zwar wieder, aber beim nächsten Start kann es dann wieder genauso sein.

Alles, was man in den Foren findet, um Thunderbird schneller zu machen, habe ich erledigt. Cache gelöscht, im abgesicherten Modus gestartet (da ist Thunderbird genauso langsam). Auch verschieben von Nachrichten in Archivordner brachte keine wirkliche Besserung.

Ich nutze Thunderbird für 7 Kalender (zum Teil lokal) und 10 E-Mail-Adressen bei unterschiedlichen Anbietern.

Als Add-on habe ich DKIM Verifyer installiert und aktiv.

Ehrlich gesagt, bin ich inzwischen ziemlich verzweifelt, was das Thema angeht. Witzigerweise lassen sich die Entwicklerwerkzeuge nicht aufrufen. Keine Ahnung, ob das vielleicht ein Indiz für den Fehler sein könnte.

Hat jemand eine Idee? Oder noch Fragen?

Herzlichen Dank.

Version 128.11.0esr (64-bit) Tbird won't download emails from server. I get a bunch of status messages at the bottom left of the screen: looking up server, connecting, checking server capabilities, etc, then everything just stops. No downloads. If I access this account via webmail, there *are* emails there that Tbird just won't download. No error messages of any kind, just those status messages in that bar along the bottom of the window. All appears well... but no messages.

On the sending sider, I can't send anything from the account either (image attached.) So there appears to be both a connection error (sending) and NO connection error (receiving.) Got me chasing my own tail in circles - - tried a couple of different email apps and they're all working as they should, same settings, both send and receive. I've never used anything other than Thunderbird and REALLY don't want to change, but if it isn't working, looks like I'll have to, like it or not. Any ideas gratefully received!

Since Thursday last week, I've not been able to receive or send e-mails.

I constantly receive the error asking for my password. It's the same for my hotmail account and my two gmail accounts.

Please help.

Need help with Thunderbird. No matter what I tried always comes back to the same problem.

Problem: Keep getting message non responding. Very buggy, difficult deleting emails (will delete after a prolong period of time > 5 sec). When typing a message there will be no characters then after a short period of time the charterer typed shows up. Sometime without and reason while using Thunderbird it close by itself.

What I have down to solve the problem: 1. Start in safe mode Thunderbird operates as expected with any issues. 2. Win 10 environment, closed all apps and made sure there was no extensions running. Made sure the only app open on the task manger was Thunderbird. NO SOLUTION FOUND 3. Download and install latest version of Thunderbird. NO SOLUTION FOUND 4. Created a new profile file. NO SOLUTION FOUND

Need help, what else is there to try short of a total Nuclear solution?

I switched from ESR to Release yesterday morning, and everything was fine for the rest of that day. But today, about 4 hours after opening Thunderbird, I've started getting login failure messages for my secondary email address. The popup says: "Login to account "maggie.jacobs@sonic.net" failed. Login to server pop.sonic.net with user name maggie.jacobs failed." I have retried multiple times but keep getting this message.

Release is set to check for messages every 10 minutes. I did not make any changes from ESR, and did not get login failure messages yesterday. I also didn't receive any emails for that address; as I said, this is a secondary address not used often. Connection security on this account is STARTTLS, unlike my primary account which is SSL/TLS. Authentication method is Normal password.

Because this started happening 24 hours after I installed Release, I suspect there has been an update to Release this morning which has caused a misconfiguration. Does anybody have any idea what is happening and how I can fix it? I will get your email responses, as they will come to my primary account which is still functioning.

How do I change the scroll bar width in Thunderbird? I can change the width in W11, but it has no effect in Thunderbird. I am using Thunderbird version 128.8.1esr 64 bit.

Thank you

I am using 64bit Windows 11 Home. This happened suddenly without any changes on my part that I know of.

Thunderbird suddenly started freezeing right after startup. The only thing I can do is login with the master password then the regular thunderbird screen opens, but I cannot click on anything. Soon after the screen is greyed out. However I can close the program down with the red "x" in the top right corner. It opens a dialog that gives me the opens to close down or wait to respond. The close option works.

The only hint I can see from the frozen screen is that the local Folder seems to have a problem as a subfolder has now multiple copies of itself. It seems to create a new copy of that subfolder every time I try to start the program.

So far I tried reinstalling/updating TB, as I assumed an update had maybe malfunctioned, (it was stuck on version 128, since I could not open TB for about a week now) but upgrading to to version 138 did not help. I also tried starting TB in troubleshoot mode, which made no difference I also tried starting TB while windows was in safe mode, which made no difference.

I read around but people that have problems with TB freezing seem to not have the freeze happen before they can do anything.

I assume something is wrong in my profile, maybe the local folder? But I have no idea to fix anything, since I cannot do anything at all in TB.

Any help would be appreciated! Thanks!

Folks, If the power to my PC fails whilst I am reading a Newsgroup, the list of subscribed newsgroups for that news server is lost. This doesn't happen very often but its a pain when it does. Dave

I recently archived a large number of messages from one of my IMAP accounts. After that, new messages show up as unread headers, but when I click on them, nothing shows up in the preview pane and the status just seems to get stuck on "Loading message". I have done the "Repair Mailbox" thing a couple of times. After a restart, Thunderbird reloads the headers from the server, but I get the same result.

сегодня столкнулся с проблемой, что не могу создать учетную запись, используя домены от mail.ru. на скриншоте показал результат моих действий: я как обычно ввел почту, поставил пароль, заранее в самой mail почте разрешил использование imap, а когда нажал готово и разрешил доступ в самом thundebird, то окошко с входом просто закрывается и пишет "не могу войти на сервер", хотя я даже не ввел пароль. это происходит со всеми доменами типо inbox и т.д, с gmail все работает нормально. помогите пожалуйста

So my microsoft office365 email account that I access with Thunderbird is almost full (think 100,000 messages), and I would like to move those messages off of the server and into local folders as backup. I've done this in the past and, while it would be cumbersome and slow, it would eventually work.

Now though, I can't seem to move more than 5-10 messages at a time to a local folder. That isn't helpful with so many emails to process! When I try larger batches, the program just balks, no error message, no emails moving, just nothing. In the past the emails would move, but then it would take ages for the mail server to catch up. Now it just isn't trying.

Any help would be appreciated!

Hello,

I am a long time user of Thunderbird and recently it seems like it is really dragging, especially when searching for emails. I am updated to 128.6.0esr (64-bit). Is there a setting I can adjust?

Thank you much!

Regards, Eric

I am trying to copy a large number of emails (about 1,000) from one subfolder to another. However, TB seems to be not up to the task. I can move one email at a time but that, of course, is not practical for my purposes. However, even if I break it down into 30 or 40 emails at a time, it copies some of them and not others. Anyone know what the problem is? I will admit that some of the emails are quite large (5-10 MB). Could this be the issue?

Working with TB 128.11.0esr (64-bit) on a Macbook running Sequoia 15.4.1.

Thanks in advance for any assistance you can offer.
