Hi Sue,

Looking on Google Groups I found a similar suggestion to do with
customproperties_change, and found this event in MSDN online, thanks for the
confirmation

You could use the PropertyChange event to watch for changes in the RequiredAttendees, OptionalAttendees and Resources properties, but be warned that you will probably get that event firing multiple times for each change in recipient.

I'm creating a form based on the Appointment form that needs to refresh a
drop-down list every time the recipients list is modified, eg if someone is
added or removed from the recipients (using the standard Scheduling tab),
this needs to modify my list box. What is the best way of doing this?

This list box is on a custom page; it doesn't actually need to be refreshed
until the tab for this custom page is shown, however I understand that there
isn't a page_open event...
