Good questions!

Didn't try safe mode, but I'm thinking the wireless doesn't work in safe
mode and thus we can't test for incoming duplicates.

As for the origin of the .PST file, that's unknown. Originally, yes,
brought over from earlier Outlook, and at the time I did the "upgrade to big
tables". But in the meantime, the laptop crashed and someone esle rebuilt it
so I have no history as to how the .PST was reconstructed.

Does the problem persist if you open Outlook in safe mode?

Start Run outlook.exe /safe
(note the space between outlook.exe and /safe)

Vista/Windows 7
Start Start Search outlook.exe /safe
(same space)

Another question, was the PST created originally in Outlook 2003 or was it
brought over from an older version?

Client has the 2003 version of Outlook (11.5608.5606) and is having
problems
on the laptop.

First, are there any updates to this version we should try?

When trying to do work in Outlook 2003, the error "The messaging
interface
has returned an unknown error. If the problem persists, try restarting
Outlook."

Well, yeah, the problem persists! Restarting Outlook sometimes helps,
sometimes not.

This version is supposed to be able to handle large .pst files. Their
inbox
lists as 3.5 Gb, and the next largest is the sent folder at 286 Mb.

Recently, incoming email appears multiple times in their inbox. IOW, the
same email is repeated in the inbox.

Thx.
