Login to Server imap.comcast.net with Username Failed

Thunderbird Adgangskoder og log ind

I have the latest Thunderbird update. Since yesterday, using imap.comcast.net, I have been getting the error "Login to server imap.comcast.net with username [removed] failed." It wants me to retry or enter a new password. I cannot get emails. I can, however, log into my Comcast email account online and see emails delivered. Thunderbird, of course, will not receive these emails.

For imap.comcast.net, port is 993, connection security is SSL/TLS, and authentication method is normal password. I have not changed any of these settings. I have not changed my password. I have done nothing to cause the problem.

I cannot find a solution online. Could someone help? Thank you!

Earlier this Sunday morning, Thunderbird began receiving Comcast emails again as usual. Practically, I did nothing to resolve the problem. Thus, whatever happened fixed itself. Ain't modern software wonderfully aggravating?

Try this:

- Delete your saved Comcast/Xfinity password from Thunderbird's Saved Passwords. They can be found in <Settings | Privacy & Security | Passwords | Saved Passwords button>. You will find at least two entries, one for the IMAP server, one for SMTP.

- Check for saved cookies. They can be seen in <Settings | Privacy & Security | Web Content | Show Cookies button>. There may not be any there, but if there are, delete them.

Now restart Thunderbird. When it checks for mail and when you send mail, you will be prompted for your password.

This usually works, but not always. Please report back with your results.

Thanks, Lin. I just followed your directions (above) exactly. Unfortunately, I still have the same error. Of course, I entered the same password, which is still correct for online login, correctly.

Any other suggestions? Thank you.

I'm thinking Comcast was having technical difficulties, not that they would be likely to admit it. You weren't the only one having unexplainable logon difficulties - I saw at least two others yesterday. I'm glad your problem resolved itself - I was out of ideas. Hope theirs did, too.

Thanks, Lin. I too suspected a problem on Comcast's end.
