Once upon a time I've had a strange situation where messages appeared
duplicated in an Outlook hooked to a Cyrus... and for no apparent reason.
Once I saw that the messages were not actually duplicated on the disk in the
user's inbox I've nailed it to the "Copernic" desktop search engine
(http://www.copernic.com/en/products/desktop-search/index.html). Back then
Copernic would spook Outlook into seeing cross-eyed an IMAP store...
