Who is the mail provider? What are the server settings in Thunderbird?

Thanks for the help, Spectrum.net was road runner and using the same @stny.rr.com Set up is the same on the other computer that works with two emails that end in @stny.rr.com Setup the same too. 587 Description - twc, Server name - mail.twc.com, Normal Password, SSL/TLS, user name ----@stny.rr.com 993 IMAP server mail.twc.com, Normal Password, SSL/TLS, user name ---- @stny.rr.com

no help yet?

No, so why re-post if no one is interested in your issue that appears to be very common for folk using spectrum.

One computer works the other does not. Have you considered the antivirus you probably have installed on both. One allowing mail connections and the other breaking them. Just a guess of course, based on years of folk complaining that email does not work because they chose to install something to monitor their mail that only sort of works sometimes. Antivirus is perhaps the single most common cause of email issues.

Thanks. I'm new to this forum and got a notification from myself I guess so I put it on again. Still having a problem and both computers have the same antivirus on both. Spectrum says it's Thunderbird. I can login to Spectrum and get my webmail using the password I'm trying with Thunderbird and still can't get through and error wrong password or set up and the setup is the same as on the other computer.
