PDF attachments to emails are sometimes corrupt. They are not displayed when the email is opened (only a blue line is shown); after they are saved they cannot be opened (Adobe and also EDGE give a message that the file is damaged). The same attachments can be opened and saved correctly using the free Outlook application from Windows. I noticed the problem this month. The installed version of Thunderbird is Thunderbird 128.2.2 esr - but the problem also existed with version 128.2.1.

My Thunderbird randomly stops checking for email messages, and will not even check when I click 'check' (the cloud). I have to dismiss Thunderbird and restart it.

Hello,

I can't receive new emails on my Thunderbird account because every time I try to refresh my inbox, I get this message:

‘An error has occurred while saving your messages. Make sure that the file system gives you write rights and that you have enough free disk space to copy the inbox’.

No problem with webmail.

We have another computer in the office connected to Thunderbird that receives all our emails. All the settings are the same, except that we haven't updated Thundebird.

We use a POP system.

Thank you for your feedback!

When I logged on this morning and opened Thunderbird, it downloaded headers of messages but when I opened them there was no sender or content, just a code _005_BN8PR14MB2900509BCA163B950DE51AAC9AE59BN8PR14MB2900namp_--

Some time ago Thunderbird changed from downloaded header and message as one, to downloading all the headers and then downloading the message content. At the moment I can access old messages but none that have tried to download this morning.

Can anyone help please?

Hi - I am receiving strange code instead of message via thudnderbird.

For instance in thunderbird I can see this code: --Apple-Mail-B3D821E7-DE68-441A-B1BC-700C9510C7FF--

But when I log in to my online inbox I can see the content of message etc.

Is there anybody who can help with that?

Kind regrds, KK

Recently while tracking down a problem with my Optus email account regarding a message stating that my quota of storage was reaching maximum, a Optus "tech" advised that I should change mr port number in my Thunderbird account and this has resulted in the now present fault condition. I can send emails from this PC without any problems but cannot receive any. I am sending this message from another PC thyat does not have this problem. What is the correct number for the port. I have uninstalled and reinstalled Thunderbird on the problem PC, even ded a system restore without success. Send OK, no receive. Help. Cheers, Gordon Shaw

I can't find the answer online. When I receive an email message and then several other people respond to the message, how shd I set up TB so the messages responding to the original message appear on my screen with the most recent one at the top of the list of responses?

Many thanks.

Outlook is used on one PC with POP3 data retrieval. Messages are only deleted by the email service provider if they are deleted in Outlook.

Thunderbird is also used to access the same accounts with IMAP access to the online accounts. All of the messages online have been downloaded by Thunderbird.

I am comparing the .pst Outlook files, and the various Thunderbird data files stored by the PC.

The Thunderbird data files are much larger than the Outlook files. For example, the largest Outlook .pst file is 2G. But there is a Thunderbird data file that is 8G.

Any reason or problem or cleanup suggestion regarding 20G of Outlook .pst data that appears as 30G of Thunderbird locally stored downloaded IMAP data?

Hi. I am using Thunderbird 128.2.1esr(64-bit), most recent update. Recently (about 1-2 months ago approx) some of my emails have started having an attachment that does not belong with it. For example, I just received an email that I know for a fact was not sent with an attachment, however in my inbox it shows that the email has an attachment. It is always the same attachment and is always the same file name, and is a file I received about two years ago. (The fie that gets attached is a legitimate one from a trusted source. It is a pdf file, and is always the same one when it gets attached to incoming emails). I can open the attachment everytime when it shows up, so it is acting like it belongs with the specific email, even though I know it is not supposed to be there. I also noticed that when this happens there is no text in the email message, just the attachment. This happens at random times and does not seem to have any specific pattern. I use a gmail account & am connected by imap. If I go directly to my google inbox the specific email shows as normal, meaning the attachment is not with it, and the text of the email shows up. How can I fix this? I have tried compacting my folders however that has not helped. I have scanned for any malware and the scans show no issues. I do not know what else to do. Any help would be appreciated. Thank you. Rich

Email was fine until around 1. Now all of a sudden it won't send outgoing email. It just sits there and spins. This happened last week for few hours, but that was just before the latest thunderbird update. It's annoying.

Hallo Team, bisher hatte ich mit Thunderbird keine Probleme, aber kommt wie aus den nichts immer die Meldung. Anmeldung auf den Server imap.arcor.de mit dem Benutzernamen "f.heben" fehlgeschlagen. Nochmals versuchen. Obwohl ich die Meldung anklicke, erfolgt keine Anmeldung,, sondern der oben genannte Hinweis kommt wieder. Warum? Muss ich etwas reparieren? Mit freundlichen Grüßen Franz Hebenstreit

when I select multiple msgs using the shift-arrow keys and hit delete an error pops up that says "msgs could not be moved or copied to the trash folder because writing to the folder failed. To gain disk spaces, from the file menu, choose empty trash, and then compact folders, and try again"

I've done this and it still does not work. I can delete msgs 1 at a time but when I get so many a day that takes a while.

I've tried reinstalling thunderbird to no avail.

Thanks!

I need to talk or chat with someone who can walk me thru a solution. Your online helps are beyond my comprehension. When I try to send, or reply to, a message, I get a screen saying "Password required for outgoing (SMTP) server.twc.com." HELP!

While transferring Mozilla Thunderbird from my old MAC computer (OS 10.11, TB 78.14) to my new MAC computer (OS 12.7.6, TB 128.1.1) everything went well except that the “inbox” for 2 of my main accounts were not placed at the top of the left hand column with my other account inboxes. I found them in the account “envelopes” at the bottom of that left hand column. 1. How can I move them back to the top of the left column under the “main general inbox”? 2. How can I reorder these inboxes so that my main inboxes are at the top? Any help would be greatly appreciated. Thanks.

As the title says, when I enable the "Digitally sign" option for OpenPGP in a new mail, I get "Sending of the message failed" when trying to send, but if I disable only this option, then the message sends successfully.

That is the case whether I encrypt or not the message.

The versions of Thunderbird I tried where: 115.14.0 and 128.1.1esr.

Please, explain me (with pictures) what should I do, to be able to read my received emails in Tb

Current version 128.2.1 on Windows 11 and having and having a problem where all current emails with attachments are previewing to an much older email attachment. Tried re installing. This just started recently

Jeg har i adskillige år brugt Mozilla Thunderbird. Har ikke haft problemer før nu. Nu kan jeg pludselig slet ikke åbne den på min pc.( Windows). Fungerer fint på min mobil. (android). Får beskeden: Programmet kunne ikke starte, fordi side om side konfigurationen er forkert. Flere oplysninger i programmets hændelseslogfil eller ved at bruge kommandolinjeværktøjet sxstrace.exe.

Kan ikke se hændelseslogfil når jeg ikke kan åbne den. Kommandopromt siger: sxestrace.exe. ukendt

I have an email contact who uses alias emails to include team members as CC. Such an alias can have the form

  !wawProdAIProjects@domainsample.com

However, the "!" in the local part seems to cause Thunderbird to modify the email address by adding double quotes around the local part:

  "!wawProdAIProjects"@domainsample.com

While both versions seem to be legitimate, my contact's incoming mail server considers the "modified" version with the double quotes as "undeliverable".

So now I am wondering if and how I can stop Thunderbird from adding those double quotes? Any ideas?

Thanks a lot!

Thomas
