title: How do I connect to my Teamproject, after I changed my primary Account Alias?
body: <p>A few days ago I changed my primarly alias for my Microsoft Account. Now I want to checkin my code, and get some error messages:</p>
  <blockquote>
  <p>An attempt to communicate with Visual Studio Team Services failed because a token could not be retrieved.</p>
  <p>You are anot authorized to access [...]</p>
  </blockquote>
  <p>Here is a picture of it:</p>

  <p>As suggested, I already tried re-entering my credentials. But this has no effect. I already tried closing Visual Studio, restarted my PC, but nothing helps.
  How can I solve the problem?</p>
