Avoid to edit a useremail after a record creation

[areyes]

Appreaciate your help on this. 

When a record is created, I have set the USEREMAIL() function to get the user email of the record creator, but later when I need to edit the record, the useremail gets modified and is replaced by my useremail. How can I do to keep the initial useremail and not get modified when the record is edited? I tried to uncheck the Edit option but an error says that when there is a formula the record cannot be read only.

Please move the expression USEREMAIL()  to the "initial value" setting of the column settings and make the editable_if setting as FALSE
