Thunderbird suddenly says "authentication failed" for my rocketmail email. Was working fine up til now. I can still log into the email directly via Yahoo. Any ideas on how to fix this.

Are you using authentication method of oauth in Thunderbird to connect to yahoo? (check account settings > server settings) You probably need to be.

Hi Matt, thanks for responding -- It was set to "normal password" but it's been working fine up til just now (which seems weird?). I just changed it to oauth2, and Hallelujah! - it seems to have fixed it. THANK YOU!! :D
