After further investigation, it appears that the message-id generated by
Outlook 2003 has the originating host name on the RHS (after the @), unless
the sending machine is a member of a Server 2003 AD domain in which case the
domain name is used which increases the risk of a collision (especially if
the LHS is copied!).
