private Calendar items

[bert]

Hi,

I am writing a C++ program that communicates with Outlook. I want to
know whether a person is busy at that time. To know this I do
CalendarFolder->GetItems(); and then a CItems->Find(). This work fine
for normal Calendar items, but it does not return Calender items which
are marked private. I understand that I can not see the content of a
private Calendar item, I just want to know whether a person is busy.
Recipient->FreeBusy() is not an option because the first parameter
'DATE' is such an old type that I can find no way to set it.
Is it possible to know if a person is busy because of a private
calendar item? With what function?

Thanks,
Bert
