Also, in trying to fix the problem myself, I have made things worse.
Now, despite the View being set to "Received, Grouped, and "Hide marked for
delete"", the messages which are marked for deletion are still being
displayed in the index (with the line through them).
I am pretty sure I did this when I went to the "Customize" and saw a filter
in place and removed it. How can I fix this that I screwed up?

Hmmm. I spoke too quickly. After wiping out the OL settings files and
allowing OL to reset them all (which included rebuilding all the settings
that the user likes), things worked fine .... yesterday.
Last night the user logged off. After logging in this morning, the same
problem is back.
That is, when she double clicks on a message with an attachment, the
message is being automatically marked for deletion.
It's been ages since I last tried to contact MS tech support, but I believe
that is my next step (I'm not looking forward to this). Anyone care to give
pointers on how to even begin contacting them for this problem?

Solved (for real this time).
Giving the answer since a few folks emailed me privately saying they were
experiencing a similar problem.
Short answer: the messages were being marked as "junk" by Outlook's
anti-spam filters. Setting the Junk Mail rules to "don't filter" solved
the problem. Alternatively, adding the address to the "trusted senders"
would also have fixed the problem.
Longer answer: Something I hadn't noticed is that Outlook has different
menu options for it's junk mail than it's "user defined rules". The "user
rules" are under Tools | Rules.... But the Junk Mail settings are under
"Actions" ("Actions"?? WTF is "actions". Arg!).
The default setting is "low", but apparently that is enough to catch email
generated by our Xerox printer/scanner/copier which sends it's scan jobs as
a .pdf attachment to the user.
