Yep, it makes sense.  But you don't want to use eval for this.
It's slow and you're likely to make mistakes with it.  Try something
like this instead:

  name = 'OUTLOOK'
  print elements[name]

Once you understand that, try this one:

  def follow_path(object, path):
      result = object
      for name in path.split():
          result = result[name]
      return result

  path = "OUTLOOK CREATEDATE"
  print follow_path(elements, path)
