Once Cortana is searching for available times, it isn't clear whether my last instructions to it triggered some action. For example, I was asked for direction after Cortana found that some people on my attendees list were out of office. I replied stating that Cortana should schedule the meeting regardless, however, that action was never registered. It would be useful to get some UX feedback from the scheduler about what state it is currently in so that the user can have a better understanding of what is needed.
