How do I remove an email address that is no longer vaild for the iTunes Store? A really old email address keeps popping up on my iPhone, the email address is not valid and I have no idea what the password was. It's been over two years.

Hello tcnolen1,

It sounds like you are trying to change the Apple ID logged into the iTunes & App Stores on your iPhone. Use these steps:

Changing your Apple ID account

Tap Settings > iTunes & App Stores, then tap the Apple ID signed in.

Sign out of the current Apple ID account and then sign in with another account or create a new Apple ID.

You can find the full article here:
