I had two emails on my Thunderbird. I deleted one by mistake. The G Mail account still works. I tried to reenter my Spectrum Account and I keep getting that my configuration user name or password are wrong. I checked all settings and they appear to be correct. I also deleted the account and tried reinstalling it and got the same result. I also tried to enter a new email account that I just got. I had the same result. Keeps asking me to reenter the password. (would be helpful if it would say why it is wrong (password, setting, etc.) I spent hours on this today. I worked with the Spectrum agent and we couldn't fix it. Bur it seems to be a general problem because I get the same result with both accounts.
