Appointment Synchronisation

[Red Twain]

Hi, I got the following problem and to me it looks like a
synchronisation errror in Outlook.

Starting point: I got several clients with OL2003 and one
exchange2003 server. All clients share a public calender
on the exchange server. When someone creates a new
appointment, all other clients get this appointment on
the next synchronisation-attempt or at the next startup
(if currently offline). When someone changes an existing
appointment these changes are saved in the local copy and
transfered on the next synchronisation attempt. The other
clients report an itemchange-event and the subject in the
explorer view has changed equivalent to the changes made
by the first user. But in the inspector (doubleclick on
the item) all info is still "old", it seems as if the
changes made are not transfered to the client. When the
user restarts outlook the changes are transfered and
persistent, the item got the latest version and an
itemchange event fires when the user opens the inspector
for the item. But no event is fired if he doen't do so
(and normally the users don't know which item to open to
get the event)

Users/clients that are currently offline and start OL2003
after the changes were made, get the itemchange-event and
when inspecting the relevant item, they get the latest
version.

So it seems to me, that OL2003 doesn't update the offline-
copy of the public calender when synchronizing, only on
startup the complete and latest version of the
appointments is copied.

Is this a known issue, is this due to some settinge i
overlooked, is this a basic-functionality of
synchronization i didn't know or is this something weird
and new??

I really need some help, because the addin that i am
developing relies on the "correct" synchronisation of
outlook.

I tested this issue with and without exchange-chache-mode
