This is my experience too.  File->Exit *does* have more luck sometimes,
whereas just closing the window may not work as expected.  Add stuff like CE
Inbox synchronization tools and the various addins people install, and it
could be anything.  For example, if our addin keeps a reference to a certain
COM object, then we end up with a COM circular reference, and Outlook never
shuts down.  Hard to call COM circular references a bug any more than they
are in pre-GC Python.

I have seen this problem enough times in the past though that I am fairly
confident that we never cause it.

Mark.
