I have used Thunderbird for years with no problem. I am using version 126.96.36.199. I have four email identities. Starting yesterday, none of my accounts can get mail. I get the following error: An error occcurred with the POP3 mail server. Mail server mail.comcast.net replied: (No more information. The error message doesn't tell me what it "replied.")
I have deleted the passwords for each account because I read on the Thunderbird support forum that this could be the problem. Now, however, it doesn't even prompt me for a password. I just get the error message. I tried to update the Thunderbird software. It says no update available. Then I downloaded and installed the latest version of Thunderbird. Same problem.
I did update to the latest version of Internet Explorer yesterday. I don't know if that could be implicated in the email problem or not.
I am able to get my email on the Comcast server and on my cell phone but Thunderbird will not work. I would appreciate any help.
