""Description: COX Server Name: smtp.mail.yahoo.com Port: 465 Connection Security: SSL/TLS Authentication method: OAuth2 User Name: your user name, duh - Mine keeps changing the user name to the last name I put into any of my 6 accounts. The only way it will send mail is if the correct user name is in the correct account (obviously). Why is it changing constantly? click OK""

I've read the "fixes" from 2023 and they do not work for me. I tried changing the DESCRIPTION to blank, didn't work. Changed them to the corresponding e-mail for the account. Didn't work. Changed it to "SMTP" with the corresponding e-mail. Didn't work.

It keeps changing the last one I edit to the one I edited before it. It's driving me crazy. Won't send mail unless the User Name is correct (obv.)

Whole mess started when forced to switch from Cox to Yahoo recently. Seems to be working other than TB changing the name as soon as I type in the next one in the next email address and then it not working until I change the User Name back to the proper e-mail address of the 6 accounts.

I downloaded Thunderbird from Microsoft store. I enter my name, email and password. The first message was "Configuration found in Mozilla ISP database", but the last message was the Error: "Unable to log in at server. Probably wrong configuration, username or password".

Email is from gmail. App version is 115.9.0 (64-bit).

I had ab account that I deleted. however the system still tries to log into the server to see if there are any new messages (for the deleted account). The account does not exist however and it cannot access the server so it hangs waiting for a response that can never come.

How can I stop Thunderbird from doing this?

When I try to send emails, I receive this message. "Sending of the message failed. An error occurred while sending mail. The mail server responded: [M1] Authentication required (6aecbed3-07a6-11ef-9de7-83bcbd00a978). Please verify that your email address is correct in your account settings and try again". I have checked as requested by this message, and everything appears to be in order. Can anyone help with this issue, please?

According to thunderbird, this event starts at 10:30 (second image) and runs until 11am (end time is correct.

Google calendar correctly has this event as starting at 10:00 (first image) running until 11am. This event is synced with google calendar and my outlook calendar (outlook has it as 10:00 as well).

It's not a time zone issue because the start time is off by 30 minutes and the end time is right. Any idea what's going on?

(Clearly a calendar sync that gets the times wrong isn't so useful.)

Have two computer with same email. My Wife's computer password got corrupted and unable to get messages. I deleted TB and deleted any reference to Thunderbird in the registry. Turn off and restarted PC, downloaded new install and run and all the setting from before automatically were in place and still could not get pass the password issue. My computer does not have any password.

My wife's PC, under setting, does not have any saved passwords or a Primary password or even the "Use a Primary Password" checked. If it is checked there is nothing there. It just will not get passed the password issue being always asked when trying to "Get Messages".

How do you get rid of all the infor, setting, password requirements and to be able to restart with a clean Thunderbird install or get passed the password issue? Making my brain hurt.

I have tried to restore a backup made with Mozbackup. This was a bad idea. I now have 2 profiles xxxdefault-beta and yyy.default. So I asked Tbird to install from yyy.default where i've got my recent emails and it tried to import without success. I humbly ask for some options. Can I merge 2 profiles ie copy them into one profie folder? Can I hide/rename the profiles then delete Tbird and install anew? I promise on my grandmothers skateboard I will never use Mozbackup again, + . As an aside in appdata,local,tbird,profiles,yyy.default,cache2 there's a whole bunch of alphacoded files. what do these do?

Thunderbird fails to access comcast.net email accounts after years of working correctly. Version 115.10.1. I have tried changing the password many times after talking to Comcast support. The best they can do is suggest I contact you.

Hi I am having problems with Thunderbird, i’m not sure if it’s to do with a windows 11 update or something else. Thunderbird is not responding also at the start of the ‘not responding’ emails from one of my accounts disappeared and then gradually started to reappear but didn’t get up to date and now just not responding st all. I have tried various things to resolve this, uninstalling and reinstalling Thunderbird, doing this and opening my pc in safe mode, doing this and opening Thunderbird in safe mode. Deleting and reinstalling the latest windows 11 update, reinstalling the latest Thunderbird update. I don’t know what to try next? I read somewhere to delete your profile, after saving it, and getting a new profile but no idea how to do this. Any help appreciated.

With Windows11 and Thunderbird 115.10.1, I am suddenly unable to send emails. It has been fine up until a few days ago and as far as I am aware, nothing has been changed.

Since installing Ubuntu 23.10 on my new desktop pc, Thunderbird is failing to see the account details in .thunderbird I copied all the files from my backup into a new account directory (/home/cfi/.thunderbird/y4xyxmli.default), a technique that has worked many times in the past, but not this time. Previously, thunderbird has simply taken the settings from the backed up files and used those to connect to my organisation's mail server. Any ideas? How can I force Thunderbird to read the old account settings?

Many thanks.

I am running Supernova version 115.5.2 and have a strange situation (maybe it's normal) when opening it.

If I have received any emails for any account in a previous session, then when I open a new session, the folders for these accounts open expanded and other accounts that did not receive any emails, remain collapsed.

I know there are others who have various issues regarding all folders expanded or collapsed but in Thunderbird before Supernova, I always collapsed all my folders and opened a new session with everything collapsed.

So can anyone tell me how to set-up Supernova so that when I collapse all my folders at the end of a session, a new session will open with all the folders still collapsed?

Thanks.

Thunderbird processes in version 125.0 are not exiting cleanly, just like it was in v115.10.1; user intervention is required via task manager to kill the the open Thunderbird processes, before Thunderbird can be restarted.

I cannot send or receive emails from my laptop on [edited] @comcast.net nor [edited] @comcast.net. I can send and receive on my iPhone at [edited] @comcast.net and don't understand why. My primary password was corrupted in the breech I believe because I haven't forgotten it but it isn't being accepted. I believe the best way to solve is for a temporary primary password to be sent to [edited] @comcast.net or texted to me at [removed phone#] or mailed to me via overnight mail. This would allow me to regain control of both accounts. Nothing in the forum addresses this issue that I saw.

Hello Folks I recent times we had to migrate from one company to another as the former company no longer provided the emailing service... At first it worked OK...then I was no longer able to get emails and the new company took me through and reset Thunderbird setup,,,once that was done all my folder structure disappeared, and all the info stored in the folders... I have been trying to sort it out, but the company has not been able to do so...and today they suggested to contact Thunderbird to see if they could help... Thank you in anticipation Franco

I deleted Thunderbird, than Installed latest version. Now in Thunderbird "Use Primary Password" is clicked so I can't reset primary P/W. Previous P/W doesn't work because there is no P/W there as far as I can see. Instructions I found: "Tools> Developer Tools> Error> etc. There is no "Error" button. Instead I get Incoming Connection (attachment) and an other screen that I don't understand. Can you help please? Thank you Ilio Pieroni
