I just download the latest version of Thunderbird, and try to add my pop mail account. But after i enter the info of outgoing server settings, the Continue button is gray and can't be clicked. once I try the test, it says that Thunderbird failed to find the settings for your email account. Can't find a server. Also i find that there is no place enter the password of my mail account.

I've had a POP3 account for years, with no problem. On a second computer I had a second TB installation that used to get its emails from a folder on the main computer. This suited our purposes very well. The second user could access all my e-mails, and her sent messages also appeared on my computer.

Alas I updated TB, and have lost this capability. Ideally I'd go back to it, but the only way forward seems to be to set up an IMAP account. I have tried this, following the instructions on the Mozilla web site. It's all very easy, but I end up with a message: "Thunderbird failed to find the settings for your email server".

I have of course checked that the settings are correct, but I can't get past this point. I have tried disabling my Internet Security (Bitdefender) but to no avail.

What should I do next, please? I'd go back to an earlier version of TB if that would enable my older method of working.

I have created a new gmail address for my wife. Would like to add this address to my existing Thunderbird Mail account so that her emails also come to my Thunderbird email account. Not sure how to add her address to do this.. Thanks

I have a new gmail account and I can't figure out how to get Thunderbird to show me messages that come in to that address. I changed some things trying to set up a second account but emails still don't arrive. I am using a desktop computer with the most recently updated Windows 11 and updated Thunderbird too. What am I missing?

Ich kann kein weiteres Emailkonto zufügen, es zeigt mir immer eine Fehlermeldung bei der Authentifizierung egal was ich erfasse...

Ich erkenne nicht, wo der Fehler liegt? Was nun?

Wie kann ich ein weiteres Email Konto hinzufügen?

My grandson got on my computer and was messing around with my email. Now when I open Thunderbird I get a pop up window that says sign in with google to continue to Thunderbird. It has my grandson's Gmail address in it and asks for a password. I can X out of it and continue to Thunderbird but it will pop up several times while I am reading my email. Why is this happening and how do I get rid of this pop up window.

I'm trying to remove a couple accounts that I no longer use in Thunderbird. A window keeps popping up asking for a password, but the mail service is no longer available. When I click on the red delete button for that account, nothing happens. I've deleted all the mail in one of them which I was able to do as I thought I might need to do that first, but I still can't delete it after that. The other one won't even let me delete the emails. How do I delete these so I stop getting asked to put in a password for accounts that are no longer valid and I don't want anymore?

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.

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 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.

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 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?

I tried to create a new account on Thunderbird with the settings that I joined, but I always have this error message : "Authentication error. Unable to log in at server. Probably wrong configuration, username or password." Is there anything I can do in the settings, or it's just impossible ?

Thank you !
