I have previously brought a domain of GoDaddy and would like to use it with your free business email service. However when setting up on your website this is the message I get?!  * This Domain is not supported or is already registered with Zoho *

My domain is: 2bmedia(dot)co(dot)uk

Please help!!
Thank you :)
