MAPIFolder.Items.ItemChange is the event to use. It will not fire however if
more than 16 items are changed at one time. That's a limitation in the
underlying MAPI.

Hi,

It is possible to bulk update several Outlook items (Outlook 2000) by
selecting the items, right clicking and selecting Categories.

Is there a way of trapping the events that fire when the items are
updated.
I can trap individual events when the item is opened/updated/closed, but
this "bulk update" approach does not seem to fire off any events that I
can
trap.

Thanks
