title: The type or namespace name 'Outlook' does not exist in the namespace 'Microsoft.Office.Inte rop'
body: <p>The project builds just fine locally, however when we attempt to have our build server build it the following error is generated.</p>
  
  <p><em>error CS0234: The type or
  namespace name 'Outlook' does not exist in the namespace 'Microsoft.Office.Inte
  rop' (are you missing an assembly reference?)</em></p>
  
  <p>The reference is correctly set in the project and the using statement is also set, the Outlook PIA has been installed on the build server.
  The using statement: <code>using Outlook_IntOp = Microsoft.Office.Interop.Outlook;</code></p>
  
  <p>We also are already using the Excel Interop and its been building fine, every reference to outlook is just like the excel references.</p>
  
  <p>Everything I have found so far point to adding the reference to the project, it is there and builds fine locally.  This error only occurs on the build server which does not have Office or visual studio loaded.</p>
  
  <p>Anyone have any ideas what might be happening here and how to get around it.  Installing Office and Visual Studio really isn't an option afforded to me.</p>
