Duplicate Attendees in Recurring Appointment

[Guest]

I am assisting a user who has a recurring meeting appointment setup in
Outlook 2003.

The main group of attendees are part of a distribution group. However, some
of the attendees in this group also get listed individually, as duplicates.

In addition, when you look at the Tracking tab, the duplicates show up as
optional attendees, but the same individual when viewed under the
distribution group shows up as a required attendee. When these individuals
send a response and accept the meeting request, the duplicate entry shows
that it has responded, but the entry under the distribution group shows that
it has not responded.

Hope this makes sense.

Thanks for any help anyone can offer.

Is there an answer for this? Seems like people have posted this question
before, and not received an answer from MS.
