Ken,

I did try and UserProperties appear to be contained in the meeting item that
is sent to a recipient; however, the object type for retrieving
UserProperties is olMeeting when the invitation arrives and olAppointment
once the invitation has been accepted. So, it makes it a bit more difficult
to manage but it is doable.

1. UserProperties is a subset of ItemProperties, although you can only
add/remove UserProperties. You check that with the IsUserProperty Boolean
property. The ItemProperties collection is zero based, the count doesn't
start at 1, it starts at 0, unlike UserProperties which starts at 1.

2. Try it and see.

1. Is the UserProperties collection simply a subset of ItemProperties?

2. When you send an AppointmentItem do UserProperty objects and
ItemProperty
objects get transferrred to the MeetingItem that arrives in the
recipient's
inbox?
