I want to Create formula field that will show Email of the User in your layout when you will create a new record
Can anyone help to how should I do
So do you want the Email Address of the current user or the user that created the record? Either way it isn't a difficult formula. Just create a formula field of type text and then insert the field you want.
For the Current User:
$User.Email
For the User that Created the record:
CreatedBy.Email
