Thunderbird Community Forum

This started happening about a month ago, without me changing my settings, which are to retain all emails unless manually deleted. Probably relatedly, copies of sent emails are not saved in the Sent folder. This is my account on yahoo.co.uk - all the emails are available when I go to yahoo through my browser, so it is just Thunderbird that is not ertaining them. I automatically accept Thuderbird software updates (now 148.0.1)

Hey all, I installed the current version of Tbird on a couple of machines for a friend, one machine worked fine for a month or so, then started giving the "unable to write the email to the mailbox, make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox" error. There is a ton of free space on his C: drive, hundreds of GB. Yesterday I installed Thunderbird to another of his PCs, also no 3rd party AV (both running Win 11), same exact error after downloading a handful of emails from a few weeks ago. To make things weirder he took his laptop (the machine that worked ok for a short time) to his office, where he has a different ISP and it downloaded all of his mail! What is going on here? I have seen plenty of threads about this error, I tried compacting, repairing the folder etc, nothing fixes the problem and Thunderbird sits there not syncing his mail. At the bottom of the window it shows that there are 200 or so emails to download, it looks like they are downloading for a bit, then it quits trying and gives the error. Is there a known cause of this seemingly common error? Are Thunderbird devs aware there's an issue that renders their software unuseable for some users? His mail account is with Brightspeed, an old centurytel.net account. Please share any tips you may have for overcoming this error, thanks!

Attempting to set up a yahoo email in thunderbird 140.9.0esr(64-bit). The goal is to have this set up on multiple workstations, so I've made the adjustments recommended per this article: https://support.mozilla.org/en-US/kb/thunderbird-and-yahoo#w_please-check-the-following-before-asking-for-support

So, the toggle for mailnews.oauth.usePrivateBrowser is set to true, site/third-party cookies are always allowed (no exceptions), and the authentication method is set to OAuth2. Using the recommended server settings for yahoo: imap.mail.yahoo.com : 993 smtp.mail.yahoo.com : 465

I am able to set up the initial OAuth. The window pops up, I log in using the account password then put in the texted code, then the window closes and I get an email confirming the login. Hitting done within Thunderbird after this has it check the password again, and it fails: "Unable to log in at server. Probably wrong configuration, username or password."

This is on a fresh Windows 11 install/fresh Thunderbird install.

Starting with Thunderbird 149, the Find command (Ctrl+F) no longer reports the number of matches; nor which match you're on, like "3 of 8 matches". I really miss that feature; please bring it back.

The Braille Institute has developed fonts that are 'hyperlegible'. How do i make "Atkinson Hyperlegible Next" the default font for headings, toolbars, message list, etc?

Thunderbird stopped syncing with my GMX email accounts (I have several) a couple of days ago. It keeps reporting that the attempted connection has timed out. I haven't changed any settings on either Thunderbird nor GMX. Any idea why and how to fix it?

Within my Outlook.com email account i have an archive folder with 36 sub folders.

In the Thunderbird app for Android only 2 of these sub folders are visible.

I cannot find any setting that to resolve this issue

Now the Message Header Customizer I was sent to about a week ago is no longer compatible with Thunderbird 149.0.

Is there another somewhere I can install?

I am moving from a win7 pc to a win11 pc. I have exported from my win7 pc fine and get a zip file of 6.6gig. I moved it to the win11 pc, where I have installed Thunderbird.

On the win11 pc I go to tools, import and it chose the import all option and press next. On the next screen there is a live button at the bottom that says next but when I press it I get nothing.

Any ideas most welcome, thanks in advance.

Hi I am having problems signing into or adding my tpg account email address through both outlook and thunderbird. My address and passwords are correct and I have used the settings in both email programs as listed by the messaging company. The error message I am getting is that on thunder bird it cannot find the settings for my emaill account and on outlook it cant find the settings. I have had ongoing issues with my tpg account, this one is a pop3, since the messaging co took over the emails when tpg moved them to there. Issues are that i get very sporadic emails ie one week working the next nothing for long periods of time. I can successfully add gmail accounts to thunderbird and outlook without problems but the tpg one is my issue. I can get tpg emails through the gmail app on my phone with pop 3 settings but nothing on thunderbird. I have contacted the messaging co for help but other than settings they cannot help and suggested coming to thunderbird for help. I prefer to use thunderbird as my email program to have everything on one would be great again. Can anyone offer advice or assistance I would greatfully appreciate it

Today I have experienced a problem downloading new messages, bulk, trash or anything else in my mail server into thunderbird. it requires my primary password and then my regular password. I just set up my primary password so I understand why it is asking for that, but I don't understand why it is also asking for my regular password before I can get access to the mail server that I am using. the regular password was set up on 6/17/24 and until today it was working fine.

I just installed Thunderbird on Linux Mint (version 22.2), when I launch the application it automatically logs into my email account on my Internet access provider. I do not want that. I want the way the old version started up: it opened my local folders on my local drive, listed previously down-loaded mail and on the left panel it listed the folders on my main (current) email account followed my the list of my other email accounts/names. The top menu let me (among other actions) select to download email to the local email directory. I do not want Thunderbird to automatically log onto my web account or sync my local directory to the online email account. When I want to read my email I want to select to download the mail from the server. When I want to access the online account I log onto it through my web host's cpanel tool.

My local hard drive has a thunderbird directory (in my home directly) from the previous Thunderbird version. It contains a subdirector labeled Mail, which contains a directory list of my email addresses, in addition to one labeled Local Folders. There is another subdirectory labeled Mail.sbd.

Is there a way the new version can be set up similar to the old version. The installed Thunderbird version is 140.9.0esr (64-bit)

How to verify the signature a incoming message with a OpenPGP signature?

I am getting the message that a part of the message might be signed. If I click on the button "open and display" there is a new window with the plain text of the whole message but the signature is not verified. What's wrong?

Thunderbird causes my machine to 'hang' from time to time, often for up to a second and usually a number of times in quick succession on each ocasion. Sometimes this happens frequently - say every 5 or 10 minutes - sometimes only after an hour or more since the past occurrance. My machine hangs completely - nothing will work, mouse, keyboard, sound, other apps etc. If I happen to be typing (into any app - including Thunderbird - when this happens, input ceases, the cursor freezes and - if the problem persists for a second or two, Windows reports "[app] is not responding" I cannot be certain, but I believe the problem occurs whilst messages are being retrieved.

This is a very serious problem as it means that I can never leave TB running as the problems it causes are not acceptable. This means I cannot deal with incoming messages without periodically re-starting TB - which is an utter PIA.

I am running Win 11 Professional on a 2-year old machine with 64 Gb of memory. I have run TB in Troubleshoot mode, I have confirmed that the problem occurs regardless or whatever other apps are running (or none) and I have proven conclusively that no other app causes any kind of similar problem.

Looking forward yto hearing if others have had the same issue and what can be done about it.

The other day previews of messages quit working in Local Folders>Inbox. New messages will show the preview, but not any of the older messages. The preview area is just blank. I drew an arrow to the preview area.

"Could not connect to server mail.atmc.net; the connection was refused" message after the installation of version 149.0. I've verified my server settings & turned off the firewall setting & it still won't connect. It worked find before 149.0 installation.
