What Password? I've been using Thunderbird for years. Never had a password; never had a need for one.

Suddenly, setting up a new computer, a password for Thunderbird is demanded. Where does one set up a Thunderbird password?

I use Verizon.net whish has long been aliased to AOL.com and “pop” it down to Tbird. This has worked flawlessly for many years. On 01/24/2025 I was routinely clearing my inbox and got this message.

“The message could not be moved or copied to folder ‘Trash on rtegethoff@verizon.net because writing folder failed. To gain disk space, from the File menu, first choose Empty Trash, and then Compact Folders and then try again.”

I assumed this meant my Inbox folder was too big so I attempted to Delete one and then a number of old emails but got this same message. I thought maybe my Junk or Trash folders were too big so I managed to Delete all messages and Compacted both folders. With both Junk and Trash folders cleared to zero, I still got the above message when I tried to Delete a message from my Inbox. When I request new messages from AOL/Verizon email server I see the first 1 or 2 messages but then the above message appears and no new messages appear in my Tbird Inbox. When I log on directly to this account that is aliased on AOL.com I see many new messages. Next I tried to send a message using Tbird to my gmail.com account and the message is received at gmail.com but there is no new entry my Tbird Sent folder. I am running WINDOWS 10 McAfee Antivirus Version 1.25.208 16.0.R125 and I turned off the McAfee software and still failed. I, also, ran the PC in SAFE MODE and still failed. I am running Tbird version 128.6.0esr. There is an update listed as 128.6.1esr and I attempted to update but again got the same above message. Any help resolving this issue would be greatly appreciate

Hi I am using the latest version of Thunderbird.

I have an extensive archive of historic emails organised by past year which have been exported to local folders on my PC. In the past a search for old email content, for example from a specific individual, has brought up a list of all the emails in the Thunderbird account both stored in the Thunderbird folder hierarchy and also in the offline files and short extracts of these have been shown. Clicking on one of these has always recovered the full email body content for that specific email from wherever it was stored.

More recently I am now finding that the body of the emails in the offline folders are no longer shown and the only way I have been able to view that email is to note the date and then physically scroll through the offline folder for that date.

Please advise.

Hi, I have been using Thunderbird for a long time and never had any issues until last Thursday. I was able to connect to my ISP email server but it ended up showing no new emails even though I know that I have emails as I am able to see them on my iPhone. So thinking that something changed, I removed my account details from Thunderbird and try to reconnect. The first stage, the detection of my ISP email server passed with no problems.

See the first attachment.

So after seeing this, I click on the Done button and then the problem arises.

See the second attachment.

Now to cover some other important information. I talked with my ISP and we checked the configuration manually that is shown in both attachments and they were completely correct to their files. No deviation in any manner. We trip POP3 and also IMAP settings and still got the same error as the second attachment. I and the tech support person from my ISP also checked the typing of my password, the original one and even the new password 10x. I also typed each character of my password slowly, just in case I typed it wrong having it visible to me and invisible to me and still got the same error as the second attachment. Also the images are from today January 29, 2025 approximately from the last 20 minutes. So this is fresh for an attempt to connect to my ISP email server, not just from some previous attempt.

Hopefully I can get a work around from the forum. Oh, one more thing I have the latest Mozilla Thunderbird that is available and that is Version 128.6.1esr (64-bit) as I had updated it before I attempted to connect to the ISP email server. I have done no uninstalls.

I have a data backup on OneDrive of everything on a different computer in my network. I want to find the Contacts file so I can import it into my other computer. Thanks

We have 1000 clients network and most of the clients having thunderbird installed (latest version) and configured , since last few months we started getting complaints that some of the local folders not showing their content mail in the system , we tried to repair folder does not work, we tried renaming .msf does not work.. when we see the some of the local folders mail they appear in the list but if you try to open it it opens blank and after trying troubleshooting steps thoes mails getting disappeared.. please assist..

Hi, I'm talking about a POP account. Every time I empty the trash, either manually or by exiting Thunderbird, the "Trash" folder is being silently deleted, and from that moment on I cannot any longer delete messages, receiving a "not enough space" error. If exit the program, and trash is set to be emptied on exit, the next time I reopen Thunderbird there is no "Trash" (Cestino in my language, I have Thunderbird in italian) folder. In my ThunderbirdProfile\Mail\Local Folders the file "Trash" of 0 byte, keep being silently deleted. To restore correct functionality, I just have to create a new "Trash" folder under "Local Folders" in Thunderbird, then a new "Cestino" folder appears, and everything is fine. But the next time I empty the Trash, the problem reappears. I suspect something linked to Windows 11, computer was recently upgraded from Win 10 to Win 11. I tried with latest version 128.7, both 32 and 64 bit. As you can see from the screenshot, after emptying Trash, the 0 byte file "Trash" is missing. Thanks Antonello

I have been asking for a help to fix this issue for a long time.

If these questions are read by the Thunderbird developers, I would hope someone would respond.

Why would an email from a sender listed in my contacts, who sends me a URL link to a website NOT colored blue and clickable as a hyperlink?

It seems like my previous requests for a fix about this issue was nothing but crickets. I am not a software developer, but retired hardware engineer, so I know a little about hyperlinks. My Email provider is AOL, and URL links come in properly as URL address, but they are 'not hyperlinks' that I can just click on to redirect me to that website, and view what is sent to me with a new tab. If I change (View Message body) AS, TEXT, then the URL address in the email turns into a hyperlink and is then clickable. Really TEXT??? Its not text, I think this is a bug. Why would I have to change from View Message AS "Original HTML", my default view each time I want to view the link. Note the email body has a URL address the for redirect with HTML code, see below.

Example: https://www.instagram.com/share/p/_8Z8M_PJR

I have been a member of this group for well over 10 years and I donate each year, but I plan to postpone any further donations until I receive support for something that should be a simple fix. AOL.com email in the inbox over the web, the URL is shown as a hyperlink, (blue), thunderbird is not showing it as hyperlink?

Community support is welcome, Eric S.

Hello - Some years ago I had old Emails recovered by the support team which were indeed fully deleted in all folders of T'bird. They directed me to the online version to achieve the recovery and it worked well. I am need again and cannot locate those instructions. To be clear, the procedure was from the support team guiding the way. Anyone have possession of these instructions or algorithm, or a better method that still works? Many thanks :)

When attempt to 'open a message – TB instead opens a Send window, using an earlier email address of mine with a provider I no longer have an account with. (but I still want to retain record of messages in TB).

I’m unsure what the pop-up yellow blocked message means – ie “unique identity matching the From address”?? Any suggestions will appreciate. Please see attach screen dump.

TB Preview panel is fine.

Background info (in Australia) My email account was with Westnet/iinet but now handled by The Messaging Co. I also use TB to access my google gmail account which continues to work fine with TB.

(Perhaps unrelated, but on same day this problem occurred (Wed 15 Jan AEST), iinet/westnest Support reset my (mobile) account in the hope system would correctly identify my replacement iPhone as 4G suitable, now that 3G network in Australia has closed down.)

Desktop Windows 10. System Restore (to day prior) tried but no change. TB version up to date. I just culled out messages not needed in case to many. I don't know max can have? Thank you

I can receive emails fine now as I had trouble for a while and didn't use Thunderbird which was a shame as I like it a lot. But now when I try and send an email it comes up with an error message. Please when answering this please keep it really simple when explaining as I am not very computer savvy. tia. I have enclosed the error message

I've searched in 'Settings' and on-line and cannot find how to set the line spacing in composing a message to single line. There are lots of answers but they all talk about the 'Composition' section in settings, which sounds logical, but it does not appear in Nebula Any help would be most appreciated Regards Greg

Hello,

am I correct that there is today no way to save the attachments of several (many!) emails of a folder in Thunderbird?

I have the same email address since the 90s and many thousands of emails, many with good memories (photos). I came from Eudora who had a great idea: an attachment folder :). From the technical side Thunderbird is probably doing this ok, but from the user perspective, it is not nice that all attachment are quite lost in the mailbox files.

I know that there are addons and other software that say that can do this task, but the most popular addon is kind of not developed at the moment I guess, and I also got errors.

What would be your recommendation for my task ?

I tried gleaning this single outgoing email of "excessive spam/sales language" (I am only thanking someone for their purchase, not asking for another); "excessive links" (they and their graphics were fine before). no "excessive emailings/quantities" (I am only sending one single email and don't do more than a few with this content ever and haven't send even one email like it in weeks); co0ntacted my internet provider (RCN Astound can't help me and told me to contact Thunderbird), I already checked POP & SMTP stuff...

"Sending of the message failed. An error occurred while sending mail. The mail server responded: [VO-101] Message blocked due to spam content in the message.. Please check the message and try again."

What do I do?

I even checked that I had the latest version of Mozilla Thunderbird: yep! :/
