iTunes email preferences
I have recently changed my email address and thus Apple ID. It works well with most apps but iTunes still has my old one in its preferences. How do I change it there?
Mac mini (Late 2014), macOS Sierra (10.12.1)
On a computer's iTunes you can log out of an account via the Account > Sign Out menu option e.g.
That will then change to a 'Sign In' option so that you can log back in with the updated version of your account
