Running Windows 10. About a week ago, TB stopped logging into ISP (Verizon Yahoo). Got TB messages to the effect that my login parameters were wrong. I verified Server Settings and Password with ISP. Tried many suggestions found online. In desperation I uninstalled and reinstalled TB (wish I hadn't). Used uninstall wizard but found filename "Thunderbird" scattered in multiple folders, some protected files I could not delete. Deleted those I could. Tried to get a clean Reinstall. Reinstalled and verified Server Settings again. I try to download email by click on "Get Messages." Receive message in lower left hand corner: "NAME.verizon.net: Host contacted, sending login information..." It times out, then I receive the following errors: "Error with account NAME.verizon.net" and "Sending of password for user NAME did not succeed. Mail server pop.mail.yahoo.com responded: Server error - Please try again later." The password recorded in "Saved Passwords/Saved Logins" is correct. I tried playing with parameters like Authentication Method, POP/IMAP, etc. No joy.

Chosen solution

  1. Are you talking about one or two email accounts? Verizon and Yahoo? Or are they the same account (not familiar with these email providers)
  2. Can you log into the web mail services of your email provider using a web browsers?
  3. Is it possible that your email provider enabled a restriction? For example for Gmail, one has to allow "less secure applications" for thunderbird to be able to connect.
