title: How to prevent "a program is trying to access data from Outlook..." warning for a trusted program
body: <p>I have a C# WinForms application on a corporate network that should behave as a drag-and-drop target for emails in Outlook, i.e. I want to be able to drag and drop an email to my application. It is using the Office Interop libraries, v14 (for outlook 2010).</p>
  
  <p>When dropping, Outlook gives a security warning, and an option to "allow access" for (1 | 5 | 10) minutes.</p>

  <p>Other applications (e.g. Visual Studio, TRIM (a records management system), etc) allow dragging and dropping without any warning on the same machine. The security settings are managed by an administrator, and I don't have access to change them.</p>
  
  <p>How do I prevent this from occuring for users of my application?  </p>
  
  <p>Is there a certificate I need to sign my app with? Do I need to register my app in some kind of registry? </p>
