When an account is deactivated, the email address will be changed to "Deactivated-<Email address>". However, in this case, a user can create another account with the business using the same email address which was deactivated before. Due to which, when we try to deactivate the new account, it throws a "The guest could not be deactivated" error.
Example:
The account with an email address dickhertz1503@gmail.com has already deactivated.
As the Guest can create another account with the same email address. In this case, the guest David has created an account with the same email address dickhertz1503@gmail.com. However, if we try to deactivate the new account, it will throw a "The guest could not be deactivated" error. 
When the "The guest could not be deactivated" error appeared on Platform?
