Thunderbird Support Forum

This has been a headache. Cox has had us migrate our accounts to yahoo. I have been able to do most of my emails, but my husband had yahoo tech help him and one of his emails will not download to the thunderbird account. The tech did a pop.mail.yahoo with this one but created new imap accounts with the other two. I tried to create a new account but it says Incoming server aleady exists. So I deleted the account, shut down Thunderbird and brought it up and tried again. I got the same message.

I am new extremely tech savvy but know a little more than my husband. If someone could please help walk me through this, I would appreciate it. Thank you.

Just trying to upload my email account. It has only partially completed the upload. Files are missing and alterations I made to my actual email account are not showing. Tried taking it off and reloading but has exactly the same errors!

Have two computer with same email. My Wife's computer password got corrupted and unable to get messages. I deleted TB and deleted any reference to Thunderbird in the registry. Turn off and restarted PC, downloaded new install and run and all the setting from before automatically were in place and still could not get pass the password issue. My computer does not have any password.

My wife's PC, under setting, does not have any saved passwords or a Primary password or even the "Use a Primary Password" checked. If it is checked there is nothing there. It just will not get passed the password issue being always asked when trying to "Get Messages".

How do you get rid of all the infor, setting, password requirements and to be able to restart with a clean Thunderbird install or get passed the password issue? Making my brain hurt.

We have been using Thunderbird with a Cox email account. Cox has just transferred all its customers to Yahoo. I want to use Thunderbird with Yahoo. How do I set that up?

As everyone here knows, Thunderbird 115 is a hot mess; sadly, as they cycle through new releases, it sometimes gets worse, not better. It appears from my update history that 115.2.3 was the most stable of the 115 versions. I'd rather go back to 102 but it seems that the profile was modified in 115 so that it is no longer compatible with 102. Thus a 102 rollback might require quite a bit of work to reimport the profile into a clean install. And I have gigabytes of important mail.

I'm not on 115.4.3 and it is close to unusable, as they screwed up regression in a major bug, and my bugzilla on it has sat unanswered, other than requesting I be nice to the devs. So as a lower-risk option might be to roll back from 115.4.3 to 115.2.3. Has anyone tried anything like that, or know the safest way? I don't know what booby traps they've planted to prevent any rollbacks. Thanks!

I bought my wife a new computer a while ago and have followed every solution I can find to trans fer the profile from her Windows 10 computer to her Windows 11. One problem is that Windows 11 repeatedly created two profiles xxxxxxxx.default and xxxxxxxx.default-release. I have made sure both computers are using Version 115.7.0. The file is much larger than 2Gb which articles suggest doing a backup. Copying the profile from Windows 10 or making a zipped backup is no problem, however, if I import or paste into either profile, nothing happens it does not let me. Once it did spend hours copying the Profile file only to say at the end this cannot be done . I should have copied the whole message. I do not use the Microsoft Cloud, is there a foolproof way of doing this and why does it create two profiles. Is it like Ubuntu where I need to be root?

Dear community, I get the error "There is no default mail client or the current mail client...". <send to> and adding files to a new message by programs like pdf printer stopped working. It worked before. Suddenly stopped.

what I did with no results: In 'Default apps' - Thunderbird ofc. 'Email' needs to be set as 'Thunderbird' reinstallation of TB 64b. installation TB 32b. HKEY_LOCAL_MACHINE\SOFTWARE\Clients\Mail​, -> Mozilla Thunderbird HKEY_CURRENT_USER\Software\Clients\Mail -> Mozilla Thunderbird HKEY_CURRENT_USER\Software\Clients\Mailto -> Mozilla Thunderbird HKEY_CLASSES_ROOT\mailto\shell\open\command -> "C:\Program Files (x86)\Mozilla Thunderbird\thunderbird.exe" -osint -compose "%1"

I will add that if I set the default Outlook, it works (Now I have deleted it).

What should I do to make Thunderbird work?

I need to download & install TB ver 31.8.0 to a newly installed system running ubuntu 22.04.

My earler installation of TB 31.8.0 on my other computer has critical information on it, running under ubuntu 14.04. It's so old that i cannot access the internet on it.

So I'm hoping to install TB 31.8.0 on this new computer, copy my TB profile from my old computer to this new computer, then do the necessary updates to this newly installed version of TB 31.8.0 to bring it up to TB vers 115

Thanks in advance!

Hello and thanks in advance to anyone offering help, very much appreciated. My partner hates computers but has to deal with them for her home based work. After long struggle she has got to grips and enjoys the functionality of Thunderbird. Her old laptop is on the way out and we got her a new upgraded machine (Lenovo windows 11). a 'friend' tried to solve a problem in the past and created a second account locally on her laptop that mirrors the incoming emails to her main BTinternet mail account. however, sometning went wrong and she hasd over 15000 duplicated emails on the second back up account. We wish to istall Thunderbird on her new machine as she doesn't like to windows mail app and noy 'enjoys' (sic) the thunderbird, especially coulering emails for easy reference. we were told that if she deletes the second account, all of the mirrorede emails on the desired/to keep BT account will also be lost. we are now wondering if it is possible to download Thunderbird onto the new machine and somehow not import the unwanted account when she signs in etc. We are hoping also that when she downloads and installs and signs in.... (the above query accepted) that her folders will also import and be populated. But!... only for the account she wants. i hope this has been clear? The server is imap from BTinternet email thnaks to all who read this far

Suddenly yesterday afternoon I became unable to download emails to Thunderbird (I can still do it in talktalk). I get a message "Unable to write the email to the mailbox. Make sure the file system allows you write privileges and you have enough disc space to copy the mailbox." I have checked there is plenty of disc space. What can I do to get the system working again? I suspect Thunderbird downloaded an update yesterday.

Hello,

I just copied my whole profile folder from a Debian 12 (Thundebird 115.7) to a Ubuntu 22.04 (Thunderbird 115.8). I expected when running it, to find it in the exact same state because, as what I'm aware of, everything is stored in the profile and nowhere else on the filesystem.

But, I found that: - my favorite folders (around 10) weren't there (well, only 1 of them) - A lot of mails were in "unseen" state (not the unread/read marker, but that star that appears the first time you open a folder for mails that has just been downloaded), where they were already seen

So my concern is about where/how are those values supposed to be stored, and why they don't seem to "migrate" as well? And, may there be some other things that didn't come too?

I was informed in the last text from a TB agent to ... "Be sure to do periodic backups." Could someone please--be specific!--tell me how to do this? And how frequently is a good idea? Thank you!

Hello Community Please help me to start again with Firefox from scratch. Last Month I downloaded Thunderbird email app and set up with a new email account using mailfence. Now I find that my mailfence email address was only a free trial and I have to pay to continue to use. I now wish to set up with my original free email with gmail. I did uninstall the Thunderbird app and then installed from fresh. Unfortunately it still has the mailfence email remembered in the Thunderbird App. How so I start again from scratch using my gmail account instead of the mailfence account that has now expired? Thank you in anticipation of you help.

During a "folder compact" one folder just was cleared and all mails are gone. Tried to copy a folder from another laptop following a tutorial. Copy seemed to be OK, paste too to the "local folders" folder. Everything, I mean all the files are there, apparently untouched, but when I open Thunderbird there is no sign of the mails.

I presume a step by step sequence of the moves to take, fool proof, both laptops, may help. Kind of "first, switch on both laptops..."

Thank you for any help.

I want to import my old emails from another thunderbird installation to this one. Both on the same computer. My old thunderbird installation had the local folders set up to point to an external SSD. I hadn't used it in a few years, and when I restarted thunderbird it lost all of my local folder information. I moved the email files (e.g. 2006 and 2006.msf) from the SSD into the local folder of the installation (I found the local folder from Troubleshooting Information). It's still not showing up. First screenshot is of the files I copied and pasted.

I also tried importing but there was an error, second screenshot is of the error.

Two same emails, but one does not accept my password, and the other does. And one shows (IMAP) at the end. I wanted to remove both and reinput as the rest of the emails. Can you assist?

Hello! I have tried to install the normal Thunderbird on my PC for months now. Everytime all it does is count more and more files, folders etc. I can't get it to install. The two screenshots were made within a few minutes. I let it install for around an hour one time and it simply counted more and more files without ever moving in progress. I really don't know what to do. Restarts, redownloads, nothing works. Maybe someone knows what's wrong. Thanks!

I added a new email account to my existing Thunderbird running other email accounts and it only loaded the Inbox from the newly added account and none of the other folders and sub-folders. What did I do wrong or not do? Grateful for any help please. Full disclosure - I had had the newly added account on this Thunderbird before but it had a load of ghost folders and was missing many others, so I removed the account (under Account settings) and then re-Added it.
