All of a sudden my comcast.net email is no longer accessible through Thunderbird,it claims I'm not using the correct password, even though none of the settings have changed. I can still access my email through webmail, using the same password. What's happened? and how can it be corrected thank you

Update: Something fixed itself, and it is currently working. Please close this thread for now.

Hi, Thunderbird updated this morning, and now I cannot access my email. I've rebooted, confirmed my server settings, and it has not fixed it.

I get a pop up message from Thunderbird stating the the connection to server pop.earthlink.net was reset. I have to reboot my PC to be able to download emails. Is there a setting I need to change? Thanks.

I have been using Thunderbird for ages now with no problem, but I suddenly realised that no recent emails were appearing from my Gmail account. I have tried everything suggested on line to resolve the problem, including uninstalling and reinstalling Thunderbird, and deleting and re-entering my acccount details but neither the IMAP or SMTP servers will connect to Gmail. I have reset all of the server settings on Thunderbird, and have checked that Gmail is IMAP compliant (which, apparently, is is now automatically). I have spent hours trying to sort this out and am just at the point of abandoning Thunderbird completely, but I am loathe to do so if there is a solution. The latest error message i have received is "Unable to log in at server. Probably wrong configuration, username or password" but I don't know what else I can check or change.

Unable to re-install gmail account in Thunderbird. Error 400 malformed server.

Two gmail accounts could not access the server. deleted one and tried to re install it without success.The accounts and passwords were not in the "saved passwords" in settings. The accounts and passwords for comcast are there and those accounts work fine.

\i seems that following some recent updates now when I open Thunderbird the screen displays the menu displaying "Inbox" AND A MESSAGE AT THE BOTTOM " sending login information" but it just hangs there. I uninstalled TB and re installed it with no difference. TB works fine on my laptop. Same server settings.

I am now unable to send or receive email, it comes up 'Thunderbird could not connect to mail server imap.gmail.com, the connection was refused'. I am unsure if it is Thunderbird or other causing the issue. I have NordVPN with split tunnelling for Thunderbird. I have Avast Premium Security which I have uninstalled and reinstalled with no change. I have Malwarebytes too. I have 2 computers, one is just a laptop for travel which I turned on and I am having the same issue with.

I am trying to add a Gmail account to Thunderbird. After clicking Continue from the configuration window, the system shows a 'Waiting for authorisation in login popup' window with a rotating circle, which eventually finishes and the window says 'Authentication error. Unable to log in at server. . . .'. As I understand it, the login popup window should be from Google asking me to confirm that it is OK for Thunderbird to connect to the Gmail server. It looks like that Google popup is being blocked. Does anyone have any suggestions as to how to get the Google permission popup to appear?

I was locked out from yahoo completely but managed to reconnect with their web client today but Thunderbird still doesn't work. my connection is POP with my ports set as: inbound.att.net 995 outbound.att.net 465 when I test the connection under settings in Thunderbird reports: Successfully established a secure connection to inbound.att.net:995. Successfully established a secure connection to outbound.att.net:465. I was at Version 146.0.1 so I upgraded to 148 with no difference

When in e-mail I get a message concerning not being able to connect I MAP settings as there are too many or something like that. (Message disapears quickly). It indicating that I should use advanced I MAP settings - all of which is way beyong my primative knowledge. Anyone throw any light on this regarding what and how to do or who to contact Thank you .

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

Hi, T/bird working fine upto Thurs night Feb 26th then yesterday morning I got pop up windows asking for login credentials. Nothing had changed. Tried logging in thru them put it errored: <<

               Something went wrong

We could not sign you in. Try again from a different device. >>

I can log into my Yahoo accounts using Firefox so passwords isn't the issue

I've read thru a number of threads on here and elsewhere but no solution so far. K9 is working on my Android phone and my wife's and her T/bird is working on her PC. Just checked versions, she is on 140.8 ESR and I'm on 148.0. Both running Win 11 Pro.

Tried changing from OAuth2 to Normal, pop window asking for password but that doesn't work

Seems to me to be an issue with Ver 148.0 as my wife's working

What am I missing?

Trying to connect to my AOL mail account on a laptop w/ win 10 & thunderbird returns the message not a valid certificate. AOL support said change the password to reset the account, which I did. Now all I get is " Host contacted, sending login info " & it the server connection times out. I can log into my AOL account with firefox. Any help will be greatly appreciated !!

Solo pochi vecchi messaggi erano presenti. Non riusciva a connettersi con Virgilio e mi chiedeva una nuova password. Non riuscivo a fare niente perché continuava a chiedere. Dovevo chiuderlo stavo pensando di usare outlook o gmail. Alle 1745 l ho riacceso e funzionava tutto. Sono riapparsi i vecchi messaggi ed arrivati quelli nuovi di oggi . Non so che dire

Hi all,

everytime I open Thunderbird I get a popup window from Yahoo finance with a server timeout message. I am unable to connect to get my emails through. I need to log on directly to Yahoo mail, which is a pain.

Hopefully someone can help me with this.

Find attached the popup image.

Regards

I moved to a new computer and successfully transferred my gmail account by moving the old profile to the new computer. But Yahoo would not connect.

I checked the setup: servers, ports and security. Using oAuth2. I deleted cookies and tried everything again.

Then I deleted the yahoo account (transferred when I moved my Thunderbird profile to my new computer). Now I can’t add it back. I have tried both imap and pop. Nothing works.

I have no problem logging in with the yahoo phone app, or Firefox. I have tried inputting a yahoo generated app password on both the new account setup and on the yahoo popup.

Yahoo account setup is looping, or hanging on the “checking password…” stage.

TBird Version: 140.7.1esr

Since yesterday I can no longer click through with hyperlinks inside an email message.

I don't understand this.

I have already tried all the troubleshooting items to no avail.

To my mind, a change was made to TBird's functionality and this is stopping the click-through to the default browser and the opening of the page linked.

Since we needed to upgrade 2 PCs to Windows 11 (1x Pro & 1x Home) nothing works anymore with Thunderbird. It has MASSIVE and unsolvable problems to connect to our Gmail account via OAuth, Not only will it ask every single time again and over again to allow the connection, but moreover even after granting access it still can NOT send (SMTP) or save or even receive (IMAP) emails. It is maga frustrating and I am currently after days and days spend to unsuccessful fix the problem are at the point to looks for a more reliable alternative (if there is any). Just as background: Our Gmail account is about 14GB big, the local Thunderbird folder around 100GB; so yes it's big, but that's another problem, there are no easy or straightforward off-line archivers any longer to effectively and still easy accessible reduce the local archive.
