Thunderbird Community Forum

I've been using Thunderbird for years at this point and it was fine, but then some time after the latest update I stopped getting new emails. I tried a bunch of random "solutions" I found on the internet and I don't remember exactly which one, but eventually I got the web portal to pop up, and it showed that I'm logged out of all my accounts (they all gmail, btw). Using this windows I was able to log back into one of them, but then it didn't popped up again to let me to log into others. For a day or so I was getting email from that one account I logged back into, but then again, suddenly, no new emails. I decided to just start over on a new profile and that's where things went from bad to worse. Now I can't even get past the initial logging process. It gives me "unable to log in at sever" over and over, no matter what I try. I tried a bunch of different config suggestions, I tried the old school way of getting a device password, I've checked if localhost was running something - it wasn't. I tried uninstalling and reinstalling, installing an older esr version (I'm on Win10, thought maybe that has something to do with it) - same thing. Unable to log in at server. I can switch back to my old profile that doesn't get any emails anymore, I've backed it up, but what's the point. Kinda feeling screwed on all fronts here.

Also, whoever is replying to people on reddit with "thunderbird employee" badge, ghosted me after one message. Great support /sarcasm.

Version: latest (whatever auto updated updated to) and 140.8.1esr OS: win10. Mail provider: gmail.

the new "experimental" account center doesn't work (version 150.0) how can I go back to the precedent account creation tool ? the option "experimental account center" is NOT checked, but I still have only the new creation account form.

Every time I start up Thunderbird, I receive a "Please verify" message from Google (see screen shot). This message refers to an email account that I deleted because I am no longer authorized to use it ["s***@old****.com]. These requests also turn up regularly if I remain connected. I cannot verify the account because the password has been changed and the verification email is no longer mine.

I have 2 other accounts on Thunderbird; one is linked to a private domain; one is an ***@gmail.com account. Both perform correctly; are configured correctly and cause no problems with passwords, etc.. Other evidence:

In Box: The s***@old****.com account is not present in the left menu window. When I go to Accounts, Settings: The s***@old****.com account is not listed. When I go to Server Settings (In or Out) there is no trace of the 's***@old****.com' account, although the other two accounts have correct settings in the 'Outgoing' server.. Previosly, this email "s***@old****.com" was also linked to my Google Account. I have deleted it from my Google Account; I have deleted it from Thunderbird as an Account. When I disconnect my Google Accounts: This has no apparent effect on frequency of Verification prompts [I close my Safari browser]. When I Close Thunderbird: The Verification prompts for "s***@old****.com" no longer appear.

It seems like Thunderbird is still trying to "Get Messages" from "s***@old****.com" and triggering the Google password protection system (?).

IS THERE A WAY TO FIX THIS IN THUNDERBIRD?

Thanks, Al

We installed Mozilla Thunderbird to manage our clients’ email accounts. Recently, we deleted one client’s email account from Thunderbird. However, a few days later, we are still repeatedly receiving login prompts asking us to re-enter the password for that account.

For your reference, the account in question is a Gmail account.

It seems the client may have changed their email password, but since the account has already been removed from Thunderbird, we do not understand why the application continues to request login credentials for it.

Could you please advise on the cause of this issue and how to resolve it?

Thank you for your assistance.

When I launch T-bird on my laptop, it shows "Enter your password for UCIm2Lqoc@gwtc.net on imap.gwtc.net:" There is no such email address. It is one that I briefly attempted to set up, then decided against it and used a different one. I have just now confirmed by telephone with my provider's helpdesk that there is no account with that name on their server.

    By simply hitting enter, that request disappears and T-bird shows me the messages for my primary email address, which works properly.
   But when I try to access my second email address, I keep getting the same request. 

First it says: "Login to account "cindyreed@gwtc.net" failed." and instructs me to "Enter your password for UCIm2Lqoc@gwtc.net on imap.gwtc.net:" And then, in response to everything I have tried so far: " Login to server imap.gwtc.net with username UCIm2Lqoc@gwtc.net failed." I would like to find out how to get out of this trap. Fortunately, I am able to access this second address on my cell-phone, but that is not much help when I am so frequently out of service area. Thank you. Plains Gardener

I would like to have an additional email on my Thunderbird account. I've tried, but the internet says I have to go to account actions button, but I cannot find such a button in my account settings. Thank you

I had a problem and deleted thunderbird. Now I have reinstalled and cant get to the allow button for account setup. It seems to be way down the page and I cant sroll down to get to it.

Just installed Thunderbird on Windows 11. Have two accounts: UN1@hotmail.co.jp and UN2@hotmail.co.jp. I created them in exactly the same way, but one of them works without problem, the other shows me "Command Error 12". After searching for a solution on the forum, I understand that none of the suggestions work. The error repeats. What can it be and is there a way to fix this error?

Thunderbird (actual version) is demanding constantly for caldav- and carddav authentications although the two mail accounts are deleted in Thunderbird. How can I get rid of these annoying messages?

To: Thunderbird Development & Support Team Subject: Gmail Account Wizard incorrectly configures SMTP, causing OAuth2 window completion failure

Dear Thunderbird Team,

I am writing to politely report a critical bug we recently identified during the automated account creation process for a Google Mail (Gmail) account. The bug prevents the Google OAuth2 authentication window from closing and ultimately halts the account setup process.

Environment Context Account Type: IMAP/SMTP (Gmail) Authentification: OAuth2 Description of the Issue When using the Thunderbird Account Setup Wizard to connect a new @gmail.com email address, the wizard automatically pulls configuration data for Google services. However, the configuration pulled for the outgoing server (SMTP) is consistently corrupted.

Specifically, the following variables are written to the prefs.js file:

IMAP Configuration: Generates correctly as imap.gmail.com with authMethod: 10 (OAuth2). SMTP Configuration: Incorrectly generates the hostname as literally ".gmail.com" (missing the "smtp" prefix) and assigns authMethod: 0 (None) instead of 10 (OAuth2). (e.g., user_pref("mail.smtpserver.smtpX.hostname", ".gmail.com");) Symptoms and Behavior OAuth2 Window Hang: Because the SMTP server address is malformed (.gmail.com) and cannot be resolved, when the user successfully authenticates in the Google OAuth2 pop-up and grants all permissions, Thunderbird attempts to finalize the setup against the non-existent SMTP gateway. This silent background failure results in the OAuth2 pop-up window spinning/hanging indefinitely with the message "Waiting for authorization". It never closes. UI Blank Dropdown Bug: If the user forces the wizard closed and attempts to view the new IMAP profile in Account Settings -> Server Settings, the "Authentication Method" dropdown is entirely blank (no text, no selectable options). This occurs because the crashing wizard also fails to inject user_pref("mail.server.serverX.is_gmail", true); into prefs.js. Without the is_gmail flag, the legacy UI is unable to map the internal authMethod: 10 integer to the "OAuth2" string in the dropdown menu. Working Solution / Workaround Used The issue is definitively tied to the automated wizard's database fetch/parsing mechanism. We were able to completely bypass this bug by closing Thunderbird and manually injecting the pristine configuration directly into the core prefs.js file:

Fixing the SMTP hostname to smtp.gmail.com. Setting mail.smtpserver.smtpX.authMethod to 10. Supplying user_pref("mail.server.serverX.is_gmail", true); to fix the UI rendering. Defining proper directory and directory-rel paths for the storeContractID. Upon restarting Thunderbird with the manual internal configuration applied, the OAuth2 pop-up window appeared on the first sync, processed the Google token instantly, and closed successfully without any hangs.

Conclusion Please investigate the ISP auto-configuration database logic that is currently generating .gmail.com as the SMTP hostname. This flaw breaks the entire OAuth2 token routing mechanism and creates a highly confusing infinite loop for everyday users trying to add their Google accounts.

Thank you for your hard work and for keeping Thunderbird an incredible email client!

Best regards.

2 inbox accounts appeared on my email program after an unplanned windows 11 upgrade when I was adding a new SSD on my laptop.

My original inbox was fwmc@nacs.net. The new addition is fwmc@nacs.net(IMAP) (that is the way it is displayed on my screen)

There are some duplicate emails in the 2 inboxes but also some unique emails in each box.

How can I get back to 1 inbox?

I have set up 2fa with my email provider (email is rdoty@gmx.com) and set an app-specific password for Thunderbird. Gmx also supports OAuth2. I have reset the passwords in Thunderbird to the app-specific one and confirmed that both ends accept cookies. The SMTP server is mail.gmx.com, port 465. Connection security is SST/TLS. The IMAP email is IMAP.gmx.com. The problem is that Thunderbird does not change Authentication Method to OAuth2. When it queries GMX it always times out or is refused. What am I missing or needs to be changed?

I have tried over and over again to add a gmail account to Thunderbird, it was there before but stopped working so I deleted it and tried to readd it but now I get an error when adding it that is it the wrong email address or password which is not the case, as I just added it to Outlook and it worked perfectly.

Any ideas?

My windows 10 Desktop C drive failed, this has been replaced and I am trying to re-install Thunderbird but I can't complete the install due to the error message shown above in my question. Please advise.

I succeed in create my addresses in thunderbird, except one, the principal of my address at Orange. They say, they recognized and then, when I click on the bottom Terminé, it's writed that there is a problem of "mot de passe" or address or "identifiant". At this part, for the others addresses, thunderbird add a linguee "identifiant" and I add a name, and after, it's OK.. But, for this address, there is no linguee "identifiant", and that don't work. I don't speak well english, I'm french, sorry. Thank you for helping me to put my address in thunderbird. Stéphanie
