SYMPTOMS

When you receive a meeting request that contains an attachment in a Microsoft Exchange Server 2003 environment, the following fields are not retained:
  • urn:schemas:mailheader:from
  • urn:schemas:calendar:organizer
This problem occurs when either of the following conditions is true:
  • You use Exchange Server 2003 Auto Accept Agent.
  • You compile and run a VBS script that uses the OnSave store sink event to call the SaveToContainer method on an ICalendarMessage object.
To process meeting requests, some third-party applications rely on the properties that are not retained. Therefore, these applications cannot process meeting requests that contain attachments.
