I have been using T-bird for years successfully until lately. We have multiple email addresses in Comcast and Gmail, but lately our passwords that we have been using and know are correct because they are written on paper and Keypass, are being changed somehow so that they will no longer work. When we look at the saved passwords in Thunderbird we see some have been changed on a certain date that we did not do, and the password listed now must be about 200 characters long. Then when we go to change the password, it may be listed as changed. Then when we try to send a message with that email address, we get an error message saying, for example, smtp.googlemail.com and a wrong username/address completely. I can find no way to correct the username email in any settings in Thunderbird. I have searched the Thunderbird HELP files many times, but am unable to find any of this addressed anywhere. After trying to fix these problems for most of 3 days now, I have get rid of Thunderbird for an email client that works correctly!!!

I had an emal logged in on Thunderbird, but I no longer need it/ don't have access to it. I have deleted the account from thunderbird, deleted the calender settings for the account, and also deleted the outgoing server settings for that particular account. However, Thunderbird keeps prompting me to provide the password for that account. How can I completely remove that particular account so it stops asking me to log back in to the account?

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.

In account setup There is an error: "Incoming Server already exist"

Damn bloody right it already exists. Or do I need to specify servers that don't exist. Just make one up or so ?

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.

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.

Hi there,

I currently have three email accounts set up in my Thunderbird client. I’d like to disable the automatic marking of messages as read—but only for one specific account (mainly for my colleagues’ convenience, as it’s a shared inbox).

In Settings > General, I see the option to turn off "Automatically mark messages as read", but this would apply to all my accounts, which isn’t what I want. I’ve checked the Account Settings for the relevant account and couldn’t find a per-account option. I also looked for an add-on that might help, but so far, no luck.

Has anyone found a workaround or solution for this? Any advice would be greatly appreciated !

Thanks in advance, Cheers.
