Error Message: "Please enter a valid email address", when removing email addresses from Customer records

Consider the following scenario:

• User receives the message when removing the email address of an existing Customer from the user interface.

• User receives the same message when updating Customer records through CSV Import to set the Email field to null.

This occurs if in the Customer record > System Information tab > Access subtab > Give Access checkbox is set to True (marked). This makes the Email field required since it is needed to log in to Customer Center. Set Give Access = False to be able to remove the email address in the Customer record.
