Thanks for reply! In Outlook 2003 and 2007 I tried Extended MAPI and in 2007
tried new PropertyAccessor API, neither of them work.
Unfortunately item.Subject = item.Subject and calling Save() method didn’t
help either.

What API are you using to add them? If it's not the Outlook object model
(obviously) then are you setting any properties from the object model after
saving your changes that might fake Outlook into thinking something has
changed on the item? One such trick is setting item.Subject to itself and
then calling the item.Save() method.

I’m trying to add non-sendable Outlook 2003 appointment attendees to the
active appointment compose window programmatically using properties
PidLidNonSendableTo (PSETID_Common 0x8536) and PidLidNonSendToTrackStatus
(PSETID_Common 0x8543).
The problem is that inspecotr does not display them immediately
immediately.
If I close appointment and open it again I can see non-sendable
recipients,
however I cannot make Outlook display them without closing inspector. I
tried
adding/removing resipients, changing properties, calling Display() method,
but nothing seems to work. Is it possible to do?
