I have set up my organizational mail account in Zoho (streetdials.com) then I have removed this domain from Zohomail.

Now I am adding this domain again and setting up in zohomail but I am having problem in setting it up. It is showing user already exist for admin@streetdials.com and email already exist for my support email id.

How can I setup my business email in Zoho Mail with master or admin email ( admin@streetdials.com), please help
