I have 2 custom domains. I tried to do referral invite from one domain to setup zoho mail for another domain. After signing up for Free plan for second domain name, it takes me to zoho mailbox of first domain always.

For ex: sarav@domain1.com invited admin@domain2.com (both domains owned by me). admin@domain2.com tried to signup. After signing up, whenever I try to login as admin@domain2.com, it takes me to sarav@domain1.com mail box.

I tried to delete domain2 from the domains list, but I could not find "domain2" in control panel of sarav@domain1.com.

Can somebody help me to either delete the domain2 registration so I can register for fresh account or fix my domain2.com email?

Thanks in advance.
