Hi Zoho Team!

I tried to register my domain with the Zoho Mail Suite here https://mail.zoho.com/orgsignup.do but I do get the notice that the domain has already been associated with a different account (not mine!).

How can I verify that I do own the domain now and register with Zoho Mail Suite then?

Domain: one2ride (dot) com

Thanks in advance
