BB Curve 8520 calendar deleted agenda
 

Hi there, first post as new to BB, only had the compny phone a week. In the calendar, agenda view I have deleted entries before today thinking I was just deleting yesterday's entry. My action hasn't deleted the calendar entries from my works calendar which sync's via Exchange, but I don't know how to reset the calendar/agenda to show past entries on my BB. I have tried battery out and no difference.
