The From field and the Organizer field are not retained in a meeting request that contains an attachment in an Exchange 2003 environment

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.
