I have successfully connected to and listened to the BeforeItemMove event on
a local (pst) calendar, but I cannot seem to get this event to fire for
shared calendars that I have open.
I am using Outlook 2007 connected to Exchange 2003.

All the code between the scenarios is the same except the code to resolve
and get the folder. Smippets below.
I have investiaged the more generic loss of scope of COM objects etc and
retain references to the folders to maintain their lifespan and as I said it
works in the local calendar but not shared calendars.
Could anyone shed some light on this for me?

TIA Simon
