About 2 months ago I started getting errors accessing Yahoo mail in Thunderbird. I deleted the account and set up my IMAP according to the recommendations on the Yahoo site for third party apps. I have TB 102.4.2 64 bit on my HP desktop running Ubuntu 22.04. I have repeatedly, at least 20 times reconfigured to no avail. I have used TB with no problem for over 10 years. Back a few months ago I did set an application password for Yahoo as well. I have looked at the solutions posted over and over again but no suggestions work. Here are my settings: Incoming mail: Server Name: imap.mail.yahoo.com Port: 993 Connection Security: SSL/TLS Authentication Method: OAuth2 User Name: Myname@yahoo.com Outgoing Mail: Server Name: smtp.mail.yahoo.com Port: 465 Connection Security: SSL/TLS Authentication Method: OAuth2 User Name: Myname@yahoo.com What gives?
