Thunderbird Support Forum

I have a problem with Thunderbird 115.11.1 with the POP3 server inbound.att.net. Someone on at at7t forum suggested changing from Userid/password to Secure Mail Key. I had previously set up two Keys with at&t, but AI have never activated them. I looked at one URL, and was able to change the settings for inbound.att.net. But I did not see anywhere to enter one of the Keys that I had generated earlier. When I tried to re-configure outbound.att.net, I did not see a OAuth2 option. I do not need to re-configure outbound at the present time, as I can send mail without a problem. But receiving mail does not work. Here is what I see in the error console log:

Here is what I changed: Thunderbird: Account Settings --> Server Setings --> Security Settings --> Authentication Method Normal Pasword -> OAuth2

                                                   Inbound.att.net: Port 995 --> 587
                                                   Connection Security: SSL/TLS --> STARTTLS 
   

What do I have to do to get one of my two Keys into the inbound Thunderbird configuration? Thanks.

Starting 3 days ago: Cannot SEND email - receiving works fine. Error message: An error occurred while sending mail. The mail server responded: Please ensure your email address and authenticating user match when sending messages. Please verify that your email address is correct in your account settings and try again.

The other odd thing is that I get asked for a password before sending which never happened before.

I followed advice given someone in 2022 - I've messed with the account settings (unfortunately) and I've changed the SMTP settings to match what Comcast recommends.

I have 3 comcast accounts; two work fine on my iPad and iPhone - one doesn't

Also I have no problem sending emails using Xfinity/Comcast Mail... but I want to use Thunderbird.

Where do I start looking?

Thanks!!

I'm sure I've made the problem worse by trying to change the setup

It has been one year, and you still have not fixed the multiselect functionality that was ruined with your Supernova "update" (which is worse in almost all aspects btw). Can you at least tell us WHEN you plan to release the fix since you locked the comments to block the countless negative ones? Is it so hard for your UX team to understand that removing multiselect functionality is like removing Ctrl+C, and Ctrl+V and set the correct priority???

Thunderbird will not allow me to file an email that has the same address as another email, but the problem is these are monthly emails from the same source with the same address.

So I've had Thunderbird for a few years. I've always had my (multiple) email accounts set to both check for new messages at startup, and check for new messages every 2 minutes (I keep it open in the background so I can be alerted ASAP). However since the last 2 updates, I can no longer fetch messages either every x minutes, or manually (Get Messages does nothing), and the only way to get new messages is closing and restarting TB completely, defeating the point of having it open in the background.

I've tried: 1) unchecking both 'Check for new messages at startup' and 'Check for new messages every x minutes' = still can't manually pull in mail with Get Messages (the status bar says it's checking, but nothing gets pulled in unless I restart TB)

2) leaving ONLY 'Check for new messages at startup' OR 'Check for new messages every x minutes' selected = nope

3) starting and restarting both TB and my PC = nope

4) checking my antivirus isn't blocking anything = it isn't

5) checking all my email account server settings/passwords are correct = they are

6) testing out Betterbird with the same accounts and seeing if it's still an issue = this also affects Betterbird

7) checking my email accounts are working in other software like Outlook/webmail = they're fine, I can get email there normally

Any ideas as to how to fix this?

Attempts to run Thunderbird 115.12.1 in Windows 11 have failed repeatedly with error message: Unable to log in at server. Probably wrong configuration, username or password.

I lost my previous PC due to an unrecoverable hard drive crash. My current email provider is AOL and I was using the Thunderbird email app prior to the crash. According to some of the O&A posed at this site, I may have to contact AOL directly for assistance.

Please advise what information I need from them to complete the installation. I know you guys are busy and I can receive current emails from AOL at this time so there is no need to rush on my account.

I like Thunderbird a lot.

Thank you. Bob Perry

I receive monthly emails from the same source but thunderbird will not let me file them because an email with the same address already exist (of course, it comes from the same source, how else can I file it?)

My sent emails from 4 of 5 accounts disappeared in Tbird but still on their servers.

Rackspace hosts 2, inmotion 1, and gmail, 2. One gmail account has the sent emails showing in Tbird. All are smtp accounts. The send file header shows the # of messages sent but there are no results showing. I have not changed any settings or new add ons for weeks so I did not do anything new. Maybe the app updated itself and there is a bug? I see in beta that compacting folders is a problem and wondering if this could be related?

Rackspace has the sent email on the servers. InMotion has sent emails Gmail has sent emails and one of the accounts still has sent email in a gmail account.

I'm repairing one of the accounts as I write but nothing showing up in sent file for that account. This is totally wacky. Thanks for any suggestions of why Tbird is wacky.

Cheers -- jim

Tbird and system specifics: System using Tbird version 115.11.1 (64-bit), STMP servers on all accounts Windows version: Edition Windows 11 Pro Version 23H2 Installed on ‎12/‎9/‎2022 OS build 22631.3737 Experience Windows Feature Experience Pack 1000.22700.1009.0

I've set up an SMTP relay with SendGrid and have added it to as an Outgoing SMTP server, but there's not password challenge and it does not appear in the from options when I go to send an email. Is there any way to do this? I have three standard email accounts set up which all appear normally in both the SMTP selection menu and from dropdown.

My e-mail account was transferred from Verizon to AOL a few years back and I never experienced any problems until one sunny morning last week when I started getting the following message: "Sending of password for user pjklim did not succeed. Mail server pop.verizon.net responded: [SYS/TEMP] Server error - Please try again later." When I typed the password in the window that popped up the message reappeared. I know that AOL went to double login identification, so I suspect it might have something to do with that. I checked all my Thunderbird settings and they all appear to be correct. I verified the pop and smtp setting through a chat with AOL. What can I do? Regards Peter

Cox.com has decided to no longer have their own email server and switched their accounts to yahoo. I can read my email directly on Yahoo, but can't get their imap to work. I changed the imap and smtp settings to yahoo. Also, the email login has changed and I changed that in Thunderbird. With Cox, the login was just "username" and now it is "username@cox.net". When I made these changes in the account settings, my email account has disappeared from the inbox, but it is still in account settings. I am using a unified inbox with several accounts.

Cox will not help me with this, and I have been on hold with yahoo for an hour with no response. I have been messing with this for two days so I hope you can help me.

I have a verizon.net email account at AOL. AOL now requires use of a one-time-use "app password" to sign in from Thunderbird. This does work but it seems like now I will have to go through this process (going to AOL web mail and requesting a new app password) every time I reboot my computer or restart Thunderbird. Is this true?

when clicking an email link this is shown

"Thunderbird is already running, but is not responding. To use Thunderbird, you must first close the existing Thunderbird process, restart your device, or use a different profile."

How do I make Thunderbird instead open a new email?

This is on Fedora

When attempting to add a second email address to Thunderbird, I get the same error message every time. I have tried updating TB and restarting my computer, here are the steps I follow, please let me know if I should include any diagnostic logs/how to get them as well.

Please note that I already have an account set up that actively works, both sending and receiving gmail. Settings > Account Settings > Account Actions > Add Mail Account Enter my full name, and email address, but leave the password field blank according to other advice on this forum, although I have also tried with entering the address. Press Continue, receive the "Configuration found in Mozilla ISP database." message. Select IMAP > Done. See a google sign in page, with my email already filled in. Select Next. Then I get a Google 400 error page, reading: "400. That’s an error. The server cannot process the request because it is malformed. It should not be retried. That’s all we know." If I close that popup window, there is now a message in Thunderbird saying "Unable to log in at server. Probably wrong configuration, username or password."

Images with more details are attached below, note that this issue persists after both an update and a restart. Please ask any questions that can help you help me. Thanks in advance.

I had to reinstall the program, I can now receive emails, but I can't send them, my ISP support indicates that I need to have the "requires server authorization" option active, I can't see that option (Google translator)

Hi,

I have changed the provider of e-mail services. The old IMAP account is already expired (not reachable).

I wanted to copy the messages from the old account to the new one. Unfortunately, it turned out that some messages contents are missing* (not downloaded locally). I acknowledge there's nothing I can do anymore to get the message contents.

However, I would definitely want to keep the records of the messages — their subject, correspondents, date and time. Can I get the message list in any form (other than taking screenshots) from Thunderbird? How to do it?

I have tested (not to work): - Copying / moving the directory from the context menu to the new account has no effect. - Dragging the individual messages has no effect as well. - After entering the Offline mode (from `File` menu) those actions result it a prompt informing that messages are not downloaded. - I tried copy-pasting the .msf file, directory and directory.sdb for the IMAP directory (with not-downloaded messages) from "ImapMail" of the profile to the "Mail" (local folders) to see if that would work, but it unfortunately haven't. - The .msf files do not contain the data (subject, correspondents, datetime).

• all the messages in question have been opened in Thunderbird. Therefore I thought I have them all on my local drive. I haven't rushed to copy the messages, because I have backed up the Profile directory (including ImapMail). Perhaps after organizing the mails (i.e. moving to appropriate IMAP directories) the local copies were deleted, and new copies (in target IMAP directories) not downloaded (as I haven't opened them anymore).

Boa tarde

Gostaria de saber como retirar o espaço duplo do paragrafo (como fossem dois enter's).

Ja pesquisei naquela soluçao Ferramentas>Opçoes>Composiçao mas nao achei.

Versao do Thunderbird: 115.12.1 (64 bits)

I keep getting the prompt* about new.thunderbird.net expiration.

Indeed, after opening https://new.thunderbird.net in Firefox, the subdomain uses the Let's Encrypt SSL certificate that expired on 22nd May 2024. This certificate list many subdomains by name.

For https://www.thunderbird.net (after opening it in Firefox), another SSL certificate file is used (issued by Google Trust Services LLC by on 13 May 2024) valid until 11 Aug 2024. It says it should apply to thunderbird.net and *.thunderbird.net, but the new.thunderbird.net still points to the old Let's Encrypt certificate perhaps?

• I know I could just allow the expired one as an exception

I just spent an hour on the phone with att and they say the problem is not theirs since I can access my account via the web interface.

Thunderbird keeps giving me this message when trying to access my email (Yahoo/AT&T). I have two email addresses with them and they both respond the same as below.

Error with account MyPrimaryBellsouthAccount Sending of password for user jarinker@bellsouth.net did not succeed. Mail server inbound.att.net responded: [SYS/TEMP] Server error - Please try again later.

I takes about 5 minutes to return this error on start up on when I use PF5 to manually check the mail.

My wife also has a bellsouth account she accesses via Thunderbird and it works fine on her laptop. So, I kind of think that rules out a home network issue.

I have some feeling that something somewhere has become corrupted in Thunderbird, but I am not sure what.

I recently converted my POP accounts to iMap. One of my local folders was corrupted. I restored a backup copy of Thunderbird that had the emails in a local folder. By local folder, I mean a folder stored on my iMac and not subject to iMap services. What I would like to do is to export the local folder from the backup TB instance and import it to my "live" TB version. Is this possible?
