Yes

I have since found the answer. You need to also place Application.DoEvents
before re-opening the form (it seems that Outlook likes to take its time
doing stuff), and the one that I nearly shot myself - the preview pae. If the
preview pane is visible the item is effectively locked no matter what you do
(nice one MS). So remove it before doing the operation and then put it back
on

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.
