How to move an existing user under my Business account?

How to move an existing user under my Business account?

Hi,

First, let me say that you folks at ZOHO are wonderful and your products are amazing! Please keep up the great work and know that many of us are willing to pay for premium business services.

Now for my question... I didn't understand how the Business account setup worked, so I created 2 of my user accounts before I understood that you create a single business account, then add users to it. Now, when I try to add these two users to my business account, I get the error message "an account already exists for that e-mail address".

Can I somehow delete these 2 user accounts so I can re-create them under the business account, or is there some way to "move" an existing user to be associated with a business account?

Thanks!
