Thunderbird won't login to ATT Yahoo mail (With new suggested settings and Oauth2 password)
Cannot access Yahoo mail for about two weeks now with T-bird. I am using the latest version with inbound.att.net and outbound.att.net with Oauth2 selected. I have an Oauth password from AT&T, when I try to use this I get a pop up that asks me for sign in credentials. When attempting sign in it says I need to enable cookies. (Firefox) I have given "cookie" permission to https://att.com, https://yahoo.com, https://login.yahoo.com. Can't get past this, any suggestions or additional permissions I might try?

Cookies must be enabled in TB Options/Privacy for OAuth2, and while TB supports OAuth2 for Yahoo accounts on imap.mail.yahoo.com, pop.mail.yahoo.com and smtp.mail.yahoo.com, I wasn't aware it would work with the att.net servers, even though AT&T mail is based on Yahoo. In that case, the usual recommendation is to use a secure mail key in place of the account password, and apply 'normal password' authentication instead of OAuth2. Is your 'Oauth password from AT&T' a secure mail key?
If you can get OAuth2 authentication to work with the att.net servers, just enter the regular account password in the OAuth browser window, and then a long oauth token will be stored in the TB password manager.

Enabling cookies worked, I was able to complete authentication and download my messages. It was the Secure Mail Key password, not OAuth2 as I previously indicated.
My T-Bird is set to OAuth2 however (POP & SMTP), but it seems to work fine now.
Thank you! Brent
After months of not being able to get my emails through Thunderbired I finally solved this problem by creating an ATT Secure Mail Key and used it in place of my ATT account password.
