When you have multiple instance running at a time it means that there is
already something wrong with your configuration. A proper configuration of
Outlook does not allow running multiple instances of the outlook.exe process
and will be nicely shut down when you close Outlook. Your request isn't a
solution for your problem but a good way to corrupt your Outlook data
(especially when running with a pst-file).

The real solution lies in one of the following;
-make sure Outlook is up to date
-make sure all your add-ins are up to date and compatible with Outlook 2000
-check Outlook behavior when started with the /safe switch

Hi Everybody

Apologies if you have seen this before, I posted it in the Access group
which was probably the wrong place

Windows XP, Access 2000, Outlook 2000

I am looking for a way to Close All Instances of Microsoft Outlook,
with VBA.

Both the "Seen One" and the unseen ones that you see when
you do a Ctrl Alt Del, and see them all sitting there in the task
manager.

I would like to have a Command Button that shuts them all.

There must be a way to do it because this neat little software product
called knockout does just that.
