Ownership of Calendar Event

[christoph.rabel]

Hi!

We have a bit of an unusual problem. We create meetings in an
application and send them to outlook using ics files by mail. This
works fine for the attendees.

Now, the person who created the event wants sometimes to update the
event in Outlook. e.g. changing time or location. But since he is not
the owner, he cannot update any Appointments.

Is it possible to tell outlook/exchange that an event received by mail
is "owned" by the user receiving it? We tried to set the Organizer in
the VEVENT to the user, but it is ignored by Outlook.

Thanks for any ideas!
Christoph
