My CEO is still using a blackberry. &nbsp;Just today, all of a sudden hundreds of emails disappeared off his blackberry. &nbsp;To be clear, not all of them, and not just old ones. &nbsp;He had emails from June 5th and older, and emails that came in after the event, but nothing in between.<br />

My CEO is still using a blackberry.  Just today, all of a sudden hundreds of emails disappeared off his blackberry.  To be clear, not all of them, and not just old ones.  He had emails from June 5th and older, and emails that came in after the event, but nothing in between.

The emails were untouched on the exchange server.
