AppointmentItem Receipient's GUID

From my Outlook AddIn, I create an appointment for:
1. Myself
2. UserBob

After the appointment is added to my Calendar folder, I have my AddIn note
the "GlobalAppointmentID" (i.e. the GUID), and send the GUID to an external
application.

Time passes, and the boss decides to use the external application to adjust
appointment dates and times for both "Myself" and "UserBob". The application
creates an "iCalendar" message and sends the message to Exchange Server using
the GUID to make adjustments to the appointment's Date and Time.

Question:
A. Is the GUID for the AppointmentItem to "Myself" == the GUID for the
AppointmentItem of "UserBob" ??
If NO
Can my Outlook AddIn get the GUID for "UserBob" ?
 
The GlobalAppointmentID (GlobalObjID property) is the same for all meeting
recipients.
 
That's great news! It means that the external application can reference the
appointment and modify the appointment time & date using the GUID. When (or
if) that happens, both users will see the NEW appointment time and date in
Outlook! That's cool!

Thank you very much for your help Ken!
