Unable to edit or delete email address

Unable to edit or delete email address

I signed up for free Zoho today. I usually am pretty good at understanding and configuring things like this, but your interface baffles me, and your online help is cryptic to say the least. I have spent hours just trying to set up a couple of email accounts in Zoho before pointing my domain MX records to Zoho. I solved some other issues on my own, but I can't figure out this latest problem: I have created two email addresses in Zoho. Let's call the first one myname@mydomain.com and the second one admin@mydomain.com.The myname address shows up in the Control Panel under User Details, User Access, and Mail Accounts, but it does not show up at all in the webmail interface (mail.zoho.com). The admin address, which I greatly regret creating, does not show up in Control Panel under User Details or User Access but does show up under Mail Accounts. It also is the address that appears in the webmail interface. I cannot edit or delete the admin address in the Control Panel. I want to use the myname address as my main Zoho address going forward and have email to that address show up in the webmail interface. If I cannot edit or control the admin address, I want to get rid of it.

I am logged in to my master Zoho account with a Gmail address. I am not using the admin address as a login, as a secondary account email address, or as an Administrator or Super Administrator.

Any help would be appreciated.
