Yes, I know that the domain currently points to another hosted Exchange service - I'm paying for it, and know exactly where it is (and look forward to canceling that service). I want to use O365, which is considerably less expensive. I want to get things set up first on O365, and then change the DNS entries (MX, autodiscover, etc.) to point to O365 when it's set up. But I can't get that far because of the error, which indicates I have orphaned services *somewhere* is the MS realm of hosted services.
My wife (and kids) use addresses in the domain, and a multi-day outage is unacceptable to her business.
