Thunderbird-Hilfeforum

I've been using TB for years with an AT&T account on a Windows 10 desktop. Two days ago all was working well sending and receiving. I stepped away for an hour (without obvious updates or changes) and surprisingly it didn't work, with TB asking for a password but not accepting it. I deleted saved passwords and tried multiple times, even changing my AT&T email password twice. I could access the email account directly through the AT&T website using those passwords.

I spoke with an AT&T support rep and he had me delete the account in TB. I did so but now can't reestablish it. I've repeatedly tried to add a new email account using credentials I know are correct, trying numerous POP3 and IMAP protocols, all without success. When TB probes the AT&T servers it says it finds those parameters, but then when it checks the password it fails, simply giving the vague message "Unable to log in at server. Probably wrong configuration, username, or password."

I've spent two days researching this problem and trying proposed solutions such as disabling firewalls and anti-virus programs, clearing Windows and internet caches, deleting saved passwords, etc. I was able to set up the account using Outlook on this computer, and if this continues I'll unfortunately be forced to abandon TB and move to Outlook or similar as a substitute. Advice would be appreciated!

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

I have been using 4 email accounts with TB for years now with no problems - 2 use IMAP gmail accounts and two POP mail accounts. In the last week, when I open TB (on a mac OS10.15.7) I am asked to enter the password for these two accounts. I have not changed the passwords for these two accounts anywhere else so I don't know why TB suddenly wants me to enter them. No matter what password I enter here, I am told the login failed and am asked to enter a new password. I enter a new password and go back to being asked for passwords again.

What password is TB looking for? Where is it stored so that I can look for it? When I go to Settings/Privacy and security/Saved passwords only passwords for the two gmail accounts are shown. Where can I find the passwords for the POP Mail Server and how do I reset them?

Hello,

i have a mailserver with a catch all function and give out only customized mail adresses. Think "paypal@domain.com".

That way i know exactly who "lost" my mail address to a spammer.

However when i want to reply, the sending mail address defaults to the one i am logged into.

Is there any possibility to configure Thunderbird, that the sending mail for the reply is equal to the receiving one i am replying to?
