title: VBA MKDIR in SharePoint fails
body: <p>Here is my issue:</p>
  
  <p>I am trying to make a folder in a SharePoint shared document library.  But it only works after I enter my credentials using the "open with windows explorer" menu item.</p>
  
  <p>My users will not understand if I tell them they need to do this first. So, my questions is either: 
  (A) is there a way to force this credential popup from VBA   OR...
  (B) is there a way to pass these credentials through VBA</p>
  
  <pre><code>myWorkbookBasePath= "\\sharepoint.buckeye.com\sites\transportation\cc\pipelineoperationreports\Shared%20Documents\" &amp; folder
  
  
  MkDir myWorkbookBasePath
  </code></pre>
