Certificate help

I was adding an edge certificate. Once I have added the URLs to the certificate and moving to finish. I’m asked to place this in CNAME DNS. Does this really we need to create a DNS record to use this kind of edge certificate?

Did you request a custom certificate for accenture.com? I’m trying to figure out why that’s in the CNAME hostname field. Why not try the Validate Using Email method?

This is an enterprise account so the emails would go to admin email that we do not have access to. Can we update the email sectionin Cloudlfare?
