Outlook 2007: Userproperty missing after sending

[Fuubah]

Hi,

i am trying to send a appointment to a second user.But after i send it. I
lost all my Userproperties, which i added before.

Now my question is : does Outlook(2007) create a new appointment item
instead of sending the original appointment ? So that the Userproperties get
lost ?

I tested the GlobalAppointmentID both are the same.
Someone know any reason why they are missing?

Thanks for your time.

This is a MeetingRequest you are sending? What you are seeing is common,
since the original request is put in your calendar as an appointment item.
Get the GlobalAppointmentID and use that to get the appointment item and add
your user properties to that.

Hi,

yes this is a MeetingRequest. Thank you

The GlogbalAppointmentID is this a unique id ?
As i said i send the Appointment to a second user, and both appointments
have the same id (local + remote outlook).

i am wondering if it could be, that the ID could already exist?

Yes, by definition a GUID like that is unique. But it was added in Outlook
2003 SP2, so only those or newer versions of Outlook will have/create/use
that value. Where it exists you can rely on it.
