Have you been calling Marshal.ReleaseComObject() on the appointments and
then setting them to null before any calls to GC.Collect() and
WaitForPendingFinalizers()?

I know it does Dmitry !

Is this a bug with Outlook 2007. Sue Certainly thought it is.! - can
anybody from MS shed any light to why it seems that sometimes only a
restart
of outlook "unlocks" the appointment item - or even better a viable
work-around. !

Thanks for the suggestion - we do that - however we loose tracking
information from the item. hmm - just thought Is there a way to copy an
item
(the whole object & all...) and then spoof its entry ID. You see the
deperate measures that we
are willing to take to make this work.
