Hello Hank

Thank you for your purchase and sorry for the delay.

If Amelia reports the email is already in use, then this email is either used by a customer or another employee. Please access Amelia/Customers and search for the email you're trying to assign to the employee. If you find a customer with that email address, this customer needs to be deleted in order to use the email for the employee.

Also, you can't assign the same email address to multiple employees. If this doesn't help, please tell us which emails you're having issues with and then provide me a temporary WP-admin (administrator) user for your site where this happens, so we could log in and take a look ‘from the inside’ as that’s the most efficient way to see and resolve the issue. 

We do not interfere with any data or anything else except for the plugin (in case that’s a production version of the site), and of course, we do not provide login data to third parties. 

You can write credentials here just check PRIVATE Reply so nobody can see them except us.
