Hi,
I am in the process of changing my company email from Exchange Online to Office 365 Small Business Premium, when I try to validate the domain with a cname or txt record, I get an error message:
"Sorry, we couldn't add the domain, empoweredcomputing.com.au is a subdomain of a domain that was already added and verified by another customer, so you can't add it to your account."
How can get Office 365 to accept that I own the domain so I can update the relevant DNS records.
Thanks very much,
Richard Barnsley
