We have an user that if he changes the text in the meeting event details and
sends it out to all participants, all looks fine initially. However, after
about half an hour, the organizer's calendar shows the old text instead of
the new one. All antendees are showing fine still, checked Sent Items and
it looked okay (the message that went out to all antendees).

What could be the problem? User is running Outlook 2003 SP3, server is
Exchange 2007 SP1.

Thanks for your help.
