DKIM is setup

DKIM is setup and having been days since, tried this last week too, but its still fails and when testing, it says " The sending domain does not have a valid DKIM entry. You can increase deliverability with a DKIM entry", this is causing issues with DMARC

What is the domain name?

nuwizo .com

The CNAMEs have been created in your DNS ok, but the Microsoft records they point to don’t exist. Did you create them in your 365 account?
