Exception meeting requests are deleted from the calendar in Outlook 2003 when recipients use a CDO 1.21 application to accept the master meeting request

Consider the following scenario:

• You create a recurring meeting request in Microsoft Office Outlook 2003.
• You modify any field in the instances of the recurring meeting request to create exception meeting requests.
• Recipients use a Collaboration Data Objects (CDO) 1.21 application to accept the exception meeting request first. Then, they use the CDO 1.21 application to accept the master meeting request.

In this scenario, the exception meeting requests are deleted from the calendar in Outlook 2003.

When the Respond method is used to accept the master meeting request, the CDO 1.21 application internally uses the GetAssociatedAppointment method. This internal call to the GetAssociatedAppointment method merges the exceptions into a temporary associated appointment and then deletes the exceptions. However, the GetAssociatedAppointment method does not save the associated appointment. Because the associated appointment is not saved, the merged exceptions are lost when the master meeting request is accepted.
