I’m trying to add my son’s iCloud email address to my apple account but says email unavailable
I am trying add my son’s iCloud email address to my Apple ID account so he can receive iMessage from my old iPad. At present he can receive emails and FaceTime but not imessage. When I try to add the email address to my Apple ID account it says email unavailable. I have only just set up this iCloud address which was available at time?? Can anyone help? Thanks 😊
