Here you can find the answer to question: "Why I cannot change my email?"
To change your email, see How can I change my email address?
If you cannot change your email, it means that email is already in use. You may have logged in previously with another authentication method e.g. LinkedIn or Facebook.
- Delete the other profile you are not using
- After that you can change your main account email
