Custom Login URL for Zoho Mail not working.

Custom Login URL for Zoho Mail not working.

Hi Team,

I am trying to use http://mail.codeandcloud.com to login to my Zoho Mail account. There I would like to display my logo.
I am following this tutorial:  https://www.zoho.com/mail/help/adminconsole/custom-url.html#alink1

I have changed the CNAME mail to business.zoho.com.

Now when I take the URL, I see it as parked by my domain registrar.

Domain Registrar: gandi.net
Zoho Mail Plan:  Mail Free

Do I need to do anything else here because
  1. I do not have a subdomain mail.codeandcloud.com
  2. I have not added a web forwarding address to mail.codeandcloud.com
Awaiting your reply.

Warm Regards,
Naveen Jose
