Yesterday I received an email from Cox saying welcome to your new email, cox email is all new. Today I am getting the enter server password screen every 5 minutes on both outlook and android. I chatted with tech support and their final answer after asking me to " turn it off and on" again was we don't support Outlook or other 3rd party products. Thank you Cox for my new email service.
