Due to issues with my old original email address I have set a new Apple ID with my new email address, I have attempted to delete my old Apple ID on my laptop and iPad. Everything is fine on my phone and iPad but on the laptop I can't remove my old email . It asks me to sign into Apple ID with my old email address if I try and do this I am told my account no longer exists. I need to remove everything with my old emails address from my laptop . I can access my new id on other devices. Thanks in advance for any help Kev
