iCal messages are delivered to the recipient but not to the journal mailbox in Exchange Server 2003 (918427)

SYMPTOMS

When you enable envelope journaling in Microsoft Exchange Server 2003, you experience the following symptoms:

An iCal message that is sent by a Lotus Notes user is delivered to the recipient. However, the journal copy remains in the local delivery queue. Therefore, such messages are not archived in the journal mailbox.
The performance of the Exchange server deteriorates because the messages that remain in the local delivery queue continue to be retried.

MORE INFORMATION

When envelope journaling is enabled, Exchange Server uses MAPI to create the envelope. Because MAPI is used to copy the properties of the message, Exchange Server tries to convert the iCal message to the MAPI format. However, the conversion process fails when the message does not follow the iCal specifications.
