Thunderbird Community Forum

For years I have had 4 email addresses using Thunderbird to access email from Yahoo AT&T currently.com email (@att.net) using Oauth2. In early March, two of the email addresses stop working. For one of the email addresses I was able to login to Yahoo mail using the User ID and Access ID and establish a new Secure Mail Key. I then went back to Thunderbird and reentered the email address with the new Secure Mail Key and was able to reestablish connection. For the second email address, Yahoo mail locked me out. I have tried to contact Yahoo support for 2 weeks by filling out their forms and have not received a response. Also I do not have a Recovery Email address. Any suggestions ?

Hello-

   Just today I received this error code when trying to sync with my Outlook account in TB. It tells me that anything under v.16.1 will not work. In the account settings it only allows me to choose from v.2.5 & 14, no 16. How do I update to ver.16?

Thanks, Bob

A few days ago I started getting a failed sign in for one of my emails. The solution seems to be that my authentication method in ≡ > Account Settings > Server Settings does not give OAuth2 as a choice. Screenshot shows what is available. All other email authentication methods have that as a choice. Is this a problem with the email program or T'bird? T'bird is 140.8.1esr (64-bit) O/S is Win11 Thanks for your help

After updating Thunderbird to version 148.0 (64-bit), my system crashed. I rebooted and tried updating again. I am now sending and receiving emails normally from only one of my three AOL email addresses. I have attempted to reconfigure the settings on the other two manually, to no avail. Can the settings be corrected automatically? Please direct me to helpful guidelines that I could follow. Thank you.
