As of 01/10/2020, Comcast email won't send or receive on Outlook 2013 or on my iPhone. Clearly not a misstep on my part but service won't accept my username and password anymore. Anybody else have this issue or know how to correct it?
What happens if you try to sign in to the account using only the webmail interface, instead of the phone mail app or Outlook? Do you get any error message?
