Cannot verify mail account on Apple devices

I’ve updated the password on Xfinity.com, and I can get to my email online. But when I try to log in with Apple Mail, it says, “Unable to verify user name or password.” The user name and password are right, and I’ve entered them correctly in Apple Mail. I’ve tried all the suggestions, like deleting the Apple Mail account and trying to set up a new one (no luck), deleting all the keychain items related to Comcast mail (still no luck), and making sure the checkbox to let third-party email apps access my Xfinity email is checked (still no luck). If this doesn’t work, I might have to look for a different email provider.

@pefurman I can understand how frustrating this would be, especially since you can successfully access your email through the Xfinity website and have already tried several troubleshooting steps. Since third-party access is already enabled, I’d recommend double-checking that Apple Mail is using imap.comcast.net on port 993 with SSL for incoming mail and smtp.comcast.net on port 587 with TLS for outgoing mail. We recommend IMAP for third-party email clients.
