"User already present in another CRM account"

"User already present in another CRM account"

Hi - I've tried to add my final user through the zoho admin panel, but am getting a "User is already present in another CRM account" error.  While I originally set up my users through the CRM, and not through the admin panel, all of the users were deleted through the CRM.  This is the only user who triggered the error when added through the admin panel.

Can we clear the email truy (at) autometrix (dot) com?
