title: How to write an outlook add-in using unmanaged code (C++/Delphi)?
body: <p>I developed an Outlook Add-in using C#.</p>
  <p>I want do completely avoid being punished for slowing down Outlook startup.</p>
  <p>Therefore I would like to create a &quot;Loader&quot;-Add-in. It's written in C++/Delphi and does nothing but enabling the C#-Add-in after itself has beeing loaded.</p>
  <p>There are a lot of hints on stackoverflow, etc. but no straightforward documentation available.</p>
  <p>Questions:</p>
  <ol>
  <li>Is there any straightforward documentation about how to write an Outlook Add-in using C++/Delphi?</li>
  <li>Is there any documentation about how to write an Add-in which enables a secondary Add-in?</li>
  </ol>
