Running Windows 10. Messages download fine on adjacent desktop computer (Windows 7).

Disabled anti-virus software to avoid possibility of blocking. Checked account settings with Comcast. Uninstalled and reinstalled Thunderbird twice. (Thunderbird reloads AFTER with emails and settings intact. How do I remove it COMPLETELY?)

Many of the messages that initially came through lacked any content. All existing messages were addressed "To: Me*. Messages identified as SPAM do come through.

By far the most common cause of mail suddenly stopping following an update is your anti virus either not coping with the version change or outright blocking this new unknown version of Thunderbird.

  • First reboot your machine to clear any invisible hangs or whatever with the anti virus. If it is still a problem check the firewall component allows Thunderbird version 45 full access to the internet..
Note the version is important. Some products such as Norton's block on any version number change so 38.0.7 will be allowed but 45 will not. For that matter 38.0.8 would also be blocked.
  • The second step is to disable scanning of email in your anti virus program. Reboot and see if that helps.
Many of the messages that initially came through lacked any content.

That you got messages, or at least message subjects proves your authenticated to the mail server and able to receive email. That what you get is garbled is not a settings issue.

All existing messages were addressed "To: Me*
That has been normal behavior since version 3. BAck in 2010 I wrote a blog post about that http://thunderbirdtweaks.blogspot.com.au/2010/08/remove-you-from-your-mail.html
Disabled anti-virus software to avoid possibility of blocking
unfortunately anti virus programs are not entirely truthful about their status. Experience has taught us that only restarting the operating system in safe mode with networking is a really sure bet it is actually disabled. See here for those instructions http://www.digitalcitizen.life/4-ways-boot-safe-mode-windows-10
How do I remove it COMPLETELY?)

While I see no reason to so that in this case, type %appdata% into the start menu search box and press enter. Delete the Thunderbird profile folder that is visible in appdata in the windows explorer window that opens. That removes all account setting, mail data and everything that makes Thunderbird "yours" restarting the application after you do that will see the new account wizard appear as a new install.
