Outlook 2002.

I have an EA here that creates meetings for her exec from her calendar.
She has been doing this for years. She then opens his calendar &
accepts the meeting 'for him'. Two weird things have recently been
happening - they both have me going hmmm...

1. Some of the meeting attendees will be missing from the exec's
calendar. They are all there on her calendar (where the meeting was
created). Um, why?

2. She creates a meeting on her calendar - someone replies with a
personal message. The reply should go to the meeting organizer (her)
but it goes to her exec's inbox instead. What?!

Please, please help. Thanks!!!
