title: Sharing a business notebook with Evernote API
body: <p>I'm getting a <code>Evernote.EDAM.Error.EDAMErrorCode.PERMISSION_DENIED</code> error on createSharedNotebook when trying to share a business notebook.</p>
  
  <pre><code>AuthenticationResult busAuthResult = _userStore.authenticateToBusiness(authToken);
  var bAuthToken = busAuthResult.AuthenticationToken;
  var bNoteStoreUri = busAuthResult.NoteStoreUrl;
  TTransport noteStoreTransport = new THttpClient(new Uri(bNoteStoreUri));
  TProtocol noteStoreProtocol = new TBinaryProtocol(noteStoreTransport);
  var noteStore = new NoteStore.Client(noteStoreProtocol);
  var notebook = noteStore.getNotebook(bAuthToken, notebookGuid);
  
  var sharedNotebook = new SharedNotebook();
  sharedNotebook.Email = "test@test.com";
  sharedNotebook.NotebookModifiable = true;
  sharedNotebook.AllowPreview = true;
  sharedNotebook.NotebookGuid = notebookGuid;
  
  noteStore.createSharedNotebook(bAuthToken, sharedNotebook);
  </code></pre>
  
  <p>The account I'm using has access to share the notebook, so I can't figure out where this error is coming from. I haven't been able to find anything on sharing business notebooks, so any ideas or links would be greatly appreciated!</p>
