<p>Once you associate an email with your Stack Exchange OpenID, you can't change it, this is <a href="/questions/tagged/status-bydesign" class="post-tag moderator-tag" title="show questions tagged 'status-bydesign'" rel="tag">status-bydesign</a>.  Says <a href="http://meta.stackoverflow.com/users/130213/kevin-montrose">Kevin Montrose</a>: </p>

<blockquote>
  <p>If you've lost access to the e-mail you registered with initially, create a new openid.stackexchange account and either add it to your Stack Overflow account (via your profile page, if you're still logged in) or create a new Stack Overflow account and email us via the Contact link so we can merge the two accounts.</p>

<p><sub>From: <a href="http://meta.stackexchange.com/a/102469/144987">How do I change the email address associated with my Stack Exchange OpenID?</a></sub></p>

<p>Rather, you have to create a new SE OpenID here: <a href="https://openid.stackexchange.com" rel="nofollow">https://openid.stackexchange.com</a> - confirm via email - then go to your Super User profile, click <code>My Logins</code> on the upper right corner, between <code>flair</code> and <code>apps</code>.  A popup appears - then click <code>add more logins</code>.  From there, click the Stack Exchange OpenID option and type your credentials, click <code>confirm</code> and you're good to go. </p>
