We would like to remove the ability for anyone to uncheck the 'Notify contact on Case Close' box on the Case Closure. I searched but there doesn't seem to be a way to make this a 'read-only' field, so the workaround I came up with was to go to Support Settings, then add Closed to the Status field on Case Details page, and then remove the Close Case button. This way, the user will never see the Case Closed page and thus will not be able to uncheck the 'Notify contact on Case Close' box.

However, the problem now is: when I set the Status to Closed, it doesn't trigger the email to Contact. Does anyone know how to trigger the email to go out EVERYTIME a Case is set to Closed status? Thanks much!
