XCLN: MAPI_E_TOO_COMPLEX Error Is Returned When Using the GetAssociatedAppointment Method of CDO

If you use the GetAssociatedAppointment method of Collaboration Data Objects (CDO), you may get the following error message:

This behavior occurs because CDO is looking for the date/time values on the meeting response message, and when it does not find a date/time value on a property, it uses the current date/time value as the default value. The values are then compared with the date/time values that are stamped by the meeting recipient. This date/time value is too old, and the MAPI_E_TOO_COMPLEX error message is returned.

This behavior is more prevalent on Microsoft Outlook 2000 clients.
