title: How can my Outlook VSTO Add-in modify the read email form?
body: <p>Depending on the text in an email being viewed, I would like my VSTO Outlook Add-in to use a modified form to display the email.</p>
  
  <p>I am able to create custom panes, but they do not show up where I want them.  I can also create Outlook form regions that are "Adjoining" and show up at the bottom.  But I have not been able to modify either of the two default forms that outlook uses to display email messages - the inspector read form, and the reading pane form used in the main outlook window.  (I apologize if I'm using the wrong terms.)</p>
  
  <p>This is where I'd like to insert some text labels and buttons and such right above the email message:</p>

  <p>Is this possible?  A <a href="https://msdn.microsoft.com/en-us/library/bb386301.aspx" rel="nofollow noreferrer">page at MSDN</a> says I should be able to customize any standard form.</p>
  
  <p>Thank for for your help.</p>
