Get Appointment owner (calendar owner)

[Mads Westen]

Hi,

I'm trying to get a hold of the person who's calendar holds an appointment.
I have the EntryID.

Person A books an appointment in his own calendar, I get the EntryID.
Person A moves the appointment to Person B's calendar without my knowledge.

Now I want to find out who's calendar (and thereby who is going to attend to
the event) there's holding the appointment.
I'm NOT using Outlook Redemption.

Best regards
Mads

When an item is moved to a different store (mailbox, PST, public folder) the
EntryID and StoreID both will change so your information is not valid. You
probably would need to set a user property on the original item with a guid
of some sort, possibly even the original EntryID and use that property to
search for the item.

In addition if you want to open another user's mailbox folders you will of
course need adequate permissions to do so.
