A user is trying to change the date and time of an outlook calendar event. She was invited and has accepted the invitation to the recurring event. She doesn't see any button saying "Send Update," instead, she sees buttons saying "Propose New Time" and "Accept." Another user who's not an invitee to the event can see the send update button inside her outlook, for this event. This is for outlook 2003, exchange 2003 and windows xp.
