Meeting invitation from Exchange - The document has no value for Created

When I receive a meeting invitation from Exchange (2003), the mail is correctly received as a meeting invitation that I can accept or decline as expected. However, the Notes document does not have a created date…

Modified (Initially), Added (In this file), and Modified (In this file) are all set.

So far, I have seen this problem with meeting requests from Exchange and Evolution (Linux based from Novell). Meeting requests from Domino R5/R6 sent over the internet seems to work fine.

Has anybody seen this?
