secondary email issue

I have an iCloud email address. My wife had a seperate email attached to my account. I have deleted her email. I cannot retrieve it please help!!.

She has a new iPhone 5s I am trying to set her up with her own standard user access to the mac with her own apple id. As a standard user her email address is rejected when I try to set up her apple id. I deleted her email from my account thinking that was the reason I could not set up her apple id. That was obviously a mistake
