Microsoft Forms error when opening Calendar appointments associated with Cisco Meeting Place.

I have MS Outlook users who are getting a Microsoft Forms error when opening a Calendar item that appears to be related to Cisco Meeting Place.  The Microsoft Forms error is:
To help prevent malicious code from running, one or more objects in this form were not loaded.  For more information, contact your administrator.
It appears under two similar situations: 1) When the user who added it, and previously had Cisco Meeting Place installed, opens the appointment.  They click okay on the error message box and then the appointment information appears.  2) When other users, such as myself, who do not have Cisco Meeting Place installed open the same appointment and then click on the 'Meeting Place' icon (Meeting Place tab in Outlook 2003) on the top in the Appointment ribbon between the Appointment button and the Scheduling button.  The Meeting Place button is only present for some appointments, probably those that were added using Cisco Meeting Place.  The Cisco Meeting Place program was removed from the user's machine because it did not appear to be working and they had other options for setting up meetings.  I presume that this problem will slowly disappear as new appointments are added using Outlook, without Cisco Meeting Place installed on the machine.  I saw a posting in the forum microsoft.public.outlook.calendaring about the same error message, but so far, no replies with any answers.
