O365 thru GoDaddy, New CRM domain authentication fails

I've tried to authenticate my domain so I can send email campaigns without the Zoho server string after my email address. No one at GoDaddy has been able to solve this matter, this is making me rethink this platform! Being able to manage all user engagement via Zoho has been amazing, now I'm considering alternatives as this is impactful to my outreach engagements.
