Admin Assistant with Calendar Issue

I have an admin assistant at my work that sets up appointments for a
number of people. She has shown me a few times now where she will send out
an appointment and if she looks at the Calendar of the person she sent the
appointment to she will see it in their Calendar. However, if she goes back
to her own Calendar and opens the instance she will not see if the person
accepted or declined the appoinment under Tracking. It simply states None
as any kind of response. It's in the proper Calendar but she cannot track
it in her own. We use O2K3 with E2K3. I ran an integ against the Public
Store but it checked out just fine. No corruption.

Any help would be great -
Thanks, Jon
