Does anyone know how I can get access to the Outlook 2003 MRU list
that contains email addresses that I have used?

%AppData%\Microsoft\Outlook\yourprofile.NK2

My Sent items has been cleared down but I have a whole load of mail
addresses to add to my contacts list and they are all in the MRU list
that pops up as I start to enter an email address to the "TO" box ...

The file is binary and it may take you a while to reverse-engineer its
contents. In the meantime, see this: http://www.ingressor.com/ and this:
