retrieve comcast email using Outlook 2021

For about a week I have not been able to retrieve my email or my or wife’s from any of our computers or phones using Outlook 2021. My ISP provider is now COX, since we move out of an area the had Comcast. I can retrieve emails using the Xfinity web.  The server responded: ‘-ERR [AUTH] Temporarily blacklisted IP Address - try again later’
