Over the last week I have been experiencing issues that prevent me from using Thunderbird on my computer. It had been working for a few weeks prior, with emails sending without issue. Without any apparent cause, and with the correct credentials set in my account settings, emails are no longer sending. They continue to be received with no issue, and I can move emails into folders etc.., which I immediately see reflected in Webmail. I get the attached error, every time I try to send an email, no matter which address I am trying to contact. I can log in to my account with the same credentials on different software on the same computer, and I have no issues with sending emails from that software, so I can't see how this would be an issue with my computer. I have tried removing the account, and adding it again. The credentials are accepted, but the issue persists. The email also works without any issues via Webmail. I have contacted the hosting company for support, but they have confirmed that this is an issue with Thunderbird. Please can somebody help?

Ubuntu 24.04.3 LTS new installation. Thunderbird 140.3.1esr (64-bit) Adding an existing account Type in My name and email address and click Continue It says it is looking up configuration and it is just looping around and does not report an error. I have waited over an hour with no result. The only way to recover is to go to the taskbar and right click Quit. It would be helpful if there were away to know what is blocking the search for the configuration.

Hello!

I am using Thunderbird 140.9.1esr (64-bit) on a Ubuntu 24.04 system. Every time I restart Thunderbird, it reverts to a little used Gmail account as the default account. I have several accounts, but my main email account is a MS365 account. I reset the setting, but every time it is restarted, the default goes back to Gmail. I have tried everything that I've found online, but cannot correct this behaviour.

Do you have any suggestions or assistance?

Many thanks!

I reinstalled thunderbird and cleared the profile folder. Then when I login Gmail, after the OAuth, it tells me "Unable to login at server. Possibly wrong configuration, username or password."

This only happens to Gmail. I also tried Outlook and this didn't happen.

I then tried running thunderbird in the terminal to see what it outputs: (image 2)

"line 232: Script terminated by timeout"

Technical information: TB version: 128.5.1-1 (arch linux aur)

On Bazzite, currently I'm running Thunderbird version 140.8.1esr.

I only have one account set up in Thunderbird, which is my iCloud email account. I followed the steps in this guide to set up my iCloud email account in Thunderbird, and it went very smooth.

No matter what I do, no matter how many times I mark all folders as read, the icon in my dock ALWAYS displays a new mail notification.

I've removed and re-added my account twice, and have uninstalled and re-installed Thunderbird from the Bazaar store. iCloud on the web also does not show that I have any new messages.

had the need to start a fresh thunderbird profile.

now I forget which setting(s) allow for thunderbird to scan the local folders, NOT the internet, for new mail.

any suggestions?

thank you

Tried to setup gmail account manually. Couldn't verify username and/or password. Thunderbird just opened a window with an URL in plain text and did nothing. Text of window below. https://accounts.google.com/o/oauth2/auth?response_type=code&client_id=406964657835-aq8lmia8j95dhl1a2bvharmfk3t1hgqj.apps.googleusercontent.com&redirect_uri=http%3A%2F%2Flocalhost&scope=https%3A%2F%2Fmail.google.com%2F+https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fcarddav+https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fcalendar&login_hint=daryl_brenton%40wycliffe.org.au

I've recently set up Thunderbird on Linux Mint 22.2 and was unable to sign into Yahoo so I tried to sign in with Firefox instead and had the same errors :-

   Something went wrong
   We could not sign you in. Try again from a different device.

OR

   We couldn’t sign you in
   Change your browser settings to continue. Try the following:
   Turn off ad blockers
   Enable JavaScript
   If you still can’t sign in, try a different device.

I can sign in with Chrome without any problems on the same workstation. Firefox version :- 147.0.4 (64-bit)

   Only Extension is Privacy Badger, but this is disabled for Yahoo.com

Thunderbird version :- 148.0 (64-bit)

   No extensions - as installed from Thunderbird download site

I'm not having any issues signing into any other websites / email accounts (Google, Hotmail).

I notice on the support website :- https://support.mozilla.org/en-US/kb/thunderbird-and-yahoo it says "Starting with version 148, Thunderbird is switching to a more secure authorization protocol PKCE for Yahoo" BUT this isn't offered in the list of Authentication methods, has PKCE been delayed? Currently using OAuth2 for Thunderbird

bold texti have a thunderbird profile on exterior drive I have installed linux mint on my PC but cannot locate the profile to use my old TB profile -either by replacing it or renaming the old profile for the linux one

I am running Linux Mint and Thunderbird 140.9.0esr (64-bit). When I try to setup my Comcast email account I get errors and the program basically stops. For example "can't access property "cleanup", this [#configVerifier] is undefined". When I allow Thunderbird to do the initial search and follow its recommendation I get this error: Error creating account Incoming server already exists

I have Tbird running on two other computers THAT HAVE BEEN TURNED OFF. I noted that if I tried setting up Tbird on my newest Mint installation, i.e., Tbird running on my Windows machine, it would also fail to make the account.

I am at a loss as to what is going on. Any ideas???

I deleted an old email address for a friend, but every time I email her, the auto-complete feature includes both the current email address and the one for her old job. I've deleted that one, and it doesn't seem to show up in the Address Book anywhere, so why does it keep coming up in the auto-complete?

It's annoying to me and to the place of employment to have the emails go to the wrong address when I'm not watching very carefully.

How can I make sure this doesn't happen again?

One of my local folders of email disappeared: it is no longer displayed under Local Folders. A few days ago while using my mouse to move a message into one of the local folders, something happened, a peculiar message briefly displayed. At the time I did <Ctrl>-Z to undo whatever happened, but I didn't see any changes. That must be when the folder disappeared, but I'm not sure.

My other folders are still in place. I can't find the missing folder inside any of the other folders (junk, deleted, archive, etc.). Yet when I search for email in one of the missing folders, the messages are found. When I go into Troubleshooting Information, there is no Profile Directory listed, and when I click on the Open Directory button, nothing happens. (I've gone through the process of transferring Thunderbird accounts to new computers in the past.) I'm using Pop!_OS 22.04 Linux and Thunderbird 140.10.0esr. I backup my laptop using Back In Time. Any idea how can I fix this?

I have been trying to add my Outlook account for about 30 minutes now. Normally, I would use the beloved legacy account creator, but that doesn't exist anymore.

But no matter what I do, I can't log in to my account. And I am pretty damn sure I got my login correct since I managed to log in to the website and all other devices with it.

And the error message is also seriously amiguous. I just need someone to help me through this..
