In MSFT Office a user gets a notification over the "Share" button when another users enters the document and begins coediting it. I am trying to capture this event so that I can pull the CoAuthor Collection off the Word application object. I cannot seem to find a programmatic event anywhere that tells you when a different user has entered an Office document. Any thoughts or insights would be appreciated!!
I could just continually poll the CoAuthor collection but it doesn't seem clean.
