In Windows 10, at the right bottom, I receive constatly "Your Cox settings are out of date"

After 2 months of looking and working with your techs at least 10 times, I found that Cox does not work with Windows Edge.  So

I kept looking.  Eurika.  I found Settings in my webmail and I answered all of the questions, changed my password and I

thought I had my settings ok with Cox.  No.  Your message keeps coming???????

Why? 

I had an unscrupulous scammer scheming as a microsoft pc fixer which ended up using my webmail. Please help.
