Thunderbird Support Forum

On Linux, closing Thunderbird also closes Firefox if Firefox was initially opened via clicking a link in Thunderbird. I don't know if this would qualify as a bug, but is there a way to have the Firefox process start independent of Thunderbird when, for example, clicking a link in an email? I'm running 115.12.0 (64-bit) at the moment, but it happens on previous versions as well.

I've been using Thunderbird as my default e-mail app for many years without a problem. A few weeks ago I was automatically upgraded to 115.1 - 64-bit. It did not upload my Address Book and my Calendar. I had to reconstruct both apps.

Also....this edition will NOT copy items to my selected location...it just adds a shortcut to my deskto.

Plus....I previously listed that I can't get specific incoming e-mails to directly to its specific sub-folder.

I am totally disappointed with this current edition and would like to go back to my previous edition which was 111 or 112. Can this be done???

Thunderbird crashed two days ago. I was with Time Warner Cable, now Spectrum. They said everything was fine on their end. What to do? Thank you! Margie Lassmann Cell: 361-648-0996

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.

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 have been using Thunderbird for many years. In Thunderbird I found this message: "Login to server inbound att.net (username) failed." When I tried to send an email I got this message: "Sending of the message failed: Unable to authenticate the Outgoing Server (SMTP) outbound att.net. Please check the password and verify the "Authentication method" in "Account Settings." [outgoing server (SMTP)]

I went to att.net and I am still receiving emails. In fact, I received an email from Mozilla Support that allowed me to sign into Mozilla Support.

Please help so I can send outgoing emails from Thunderbird.

Thank you

I have been using Thunderbird for years with ATT POP3 email. For some reason, it stopped receiving and sending emails yesterday. I keep receiving the error message, "Sending of password for user XXX@swbell.net did not succeed. Mail Server inbound.att.net responded: [SYS/TEMP] Server error - Please try again later." My email is still working when I login to the website. I have tried changing the password and that did not work. Please help.

As stated above I can receive email but cannot send email since the last update over a week ago. Also when adding a bookmark it does not show up anywhere that I can find. I seems that I have lost some bookmarks and now it shows two bookmark menu's.

I have been using Thunderbird a long time and I have emails going back about twenty years. This means that the built in import/export feature is hopeless. So I copied the entire Thunderbird folder to the new computer. I was able to transfer thousands of emails, but when I looked more closely I saw that my new Thunderbird only went back about 2 years. I would be very grateful if someone could tell a way to make it include the missing older emails.

Yesterday, Thunderbird, version 115.11.1 (64-bit) suddenly stopped sending and receiving all emails. I received the following error messages: 1. Login to server pop.mail.yahoo.com with username ***@att.net failed. 2. Login to server smtp.att.yahoo.com with username ***@att.net failed.

I reset my password, but that did not help. I am continually prompted to reset the password. I verified that the ATT.net web account is working properly, where I can send and receive emails. I also verified that the server settings are all correct.

Incoming server setting: pop.mail.yahoo.com, Port 995, Connection Security: SSL/TLS, Authentication Method: Normal Password.

Outgoing server setting: smtp.att.yahoo.com, Port 465, Connection Security: SSL/TLS, Authentication Method: Normal Password.

Could you help me resolve this problem.

Thanks very much,

I read through the previous discussion on this issue since I am suffering from the same issue of links not working as expected. I regularly need to forward messages which include links and none of the suggestions mentioned worked for me, and I do not recall this being a problem in the past.

I currently run Thunderbird 115.11.0 on Linux Mint 21.3 Cinnamon & have been using Thunderbird as my primary Email package for many years across multiple computers.

The work around is to to copy any email that is to be forwarded to the Drafts folder. Links are preserved and the message can then be edited as required and sent complete with the embedded links.

Hope this helps others who have the same problem.

When trying to retried incoming messages, I keep getting popup that ask for my password. I tried to use the hidden password in the app, which till now has always worked, but get the following message:

"Sending of password for user (parrotdise13@att.net) did not succeed. Mail Server inbound.att.net responded [SYS/TEMP] server error - please try again later."

I have browser access to my att/yahoo parrotdise13@att.net account after changing my password. But entering the new password in the above mentioned popup produces same result.

Thanks, John B.

In most recent iteration of Thunderbird, my emails arrive hours late... (They're also forwarded to other email addresses, and arrive on time there, so the issue seems to be downloading into Thunderbird). It happens also when I "download now", that is, the emails that are on the server or downloaded on my other accounts don't download to Thunderbird. This can be anywhere from 2 hours to 12 hours late.

Hello, since May I have not been able to archive messages on the @wp.pl account by years and month. The archive button does not work, and when it does work, the message goes to the general archive directory. I don't know how to fix it, please help.

Hi I am getting on a daily basis Thunderbird Not Responding, so I have to start Task Manager to close the program and the open it up again. I like this program but this issue is now on a daily basis and has been like this for a couple of weeks now. Kind regards Jim M

Thunderbird downloads emails properly when first opened but the comes up with error as per attached for subsequent downloads. It does this for all (5) email addresses I have. Every once in a while when the error message comes up, Thunderbird freezes completely and I have to force quit. (on Mac)

My calendar stopped syncing one way: when I add an event in Thunderbird, it does not appear in Google calendar. It worked fine until about a month ago. I am using version 115.11.1

Thunderbird has suddenly stopped pulling in email, please help. It just says 'Checking mail server capabilities'. I have changed no settings at all. Webmail works. Email on my phone works. So it's not the ISP or the server or anything like that. It's just on Thunderbird where I can't do anything, but I've not changed anything so I don't understand.

When I try to send email it fails and says: Sending of the message failed. Unable to communicate securely with peer: requested domain name does not match the server’s certificate. The configuration related to mail.mandyhaggith.net must be corrected.

So please can you tell me how to correct the configuration?

Thank you for any help you can offer.

Best wishes Mandy
