In more specific terms than my previous post....

Our Executive Admins manage the calendars for others. All of then have their
own mailbox as well have Editor rights to the account for the purposes of
sending and reading mail, and administering the calendar.

Recently, meetings have been sent out to multiple users in other
departments, and even though some of them accept or decline the meeting,
their status in the meeting tracker remains unchanged. The users are running
either Outlook XP and/or Outlook 2003, and Exchange 2000 SP3 on the back-end.
Are there any known issues with tracking not being updated when either a
person has Delegated rights?  Thanks.
