I have been using the same Email Address and Thunderbird for Downloading my Emails for over 10 years. Now Thunderbird will Not Install. Am getting a strange Error Message ... Authentication Error : Unable To Log in at Server. This has happened on 3 machines. Why is it now impossible to Install Thunderbird on Windows 10 machines.


My LongTime Email Address is [edited from public] @Juno.com
