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

I have had ongoing help for my question but no one has gotten back to me for four or so days now. So am resending my info as after checking and rechecking I still can not send or receive in from charter.net. Thanks!.........Candy

The correct settings for Charter are not easy to extract from their website, but another user had this problem and finally arrived at these working settings:

incoming IMAP server: imap.charter.net or mobile.charter.net port: 143 or 993 Connection security: none or SSL/TLS Authentication: Password transmitted insecurely or normal password User name: your email address

outgoing SMTP server: smtp.charter.net or mobile.charter.net port: 25 or 587 Connection security: none or SSL/TLS Authentication: Password transmitted insecurely or normal password User name: your email address

http://www.spectrum.net/support/internet/email-settings/#/mobile-email-settings

I suggest you remove the current Charter POP account and add it to TB as an IMAP account.

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

Your account 2 is set up as a POP account but with IMAP settings, and account 3 is IMAP but the connection security is SSL/TLS when it should be None. Both accounts are set to send on charter.net when it should be smtp.charter.net or mobile.charter.net.

When you add an account to TB, choose manual config. to enter the required settings.

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

Now, every time you access the server, you're transmitting your password in the clear. Congratulations.
