Well, I again rechecked everything, read forums for two hours, deleted my password and now it will not ask for a password. Would appreciate more help. Thanks!.........Candy

Since Spectrum has taken over Charter you may need to make some changes. Are you using your entire email address for a username? Read Spectrum setting here. http://www.spectrum.net/support/internet/email-settings/

I have read and reread the link that you send and checked my entries in Thunderbird so many times that my head is hurting! Right now I having the problem of not getting a sign in box after deleting my password. I've read about going to about.config to change something but can't figure that out. More help please. Thanks.......Candy

Thunderbird is not working in Safe Mode. Use AVG Anit-virus Free 16.151.8013 My other account, ludemans@centurytel. net worked fine. When I set up new account candylud@charter.net it worked for a a day. The error on my sending email says: Timed out. Thanks!..........Candy

Don't understand your instructions as my charter account is set as an IMAP and one for mobile. Something I'm missing? Thanks.......Candy

All I did was change connection security to none and it worked! Thank you so much for your help!..........Candy
