Hi Henning and Girardsc,
To address your question the rule on Free Busy updating is very simple. Unless you booked the meeting thru OWA then the Client is ALWAYS responsible for updating the Free/Busy information. There is no server process in Exchange 2003 that will update a Mapi initiated meeting request on someones Free/Busy.
Now ... you can see what you would think would be unexpected behavior because it is possible for one Outlook Client to update another users Free Busy information. This is usually in the case of delegate. Also if you have something like BlackBerry or other similar software in the organization ... many of thoses will update your calendar and I think your Free/Busy for you.
But from a Pure Microsoft stand point ... the server is Not Responsible for updating Free/Busy information (unless the information was submitted with OWA).
Hope this clears this up.
