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

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,
