email service

I'm having a similar problem. The password works in webmail but errors using Outlook on my PC and Mail on iOS. Going through the password reset link and entering exactly the same password, my email clients start working again (with no changes to the settings in those programs). A few hours later it happens again.

This is the same whether configured to use POP or IMAP

This is happening because when you reset your password you're using the same password you were previously using.  If you do this the POP/IMAP server will lock you out because your previous password has been compromised.  To prevent being locked out anymore you must use a password you have never used with Cox when resetting it.
