Here is how I do it.
Go to windows file
then aplication data file
then identities
then open the long number file
then open microsoft file
then open outlook express file
here is where all of your old e-mails send and recieved are at, also subscribed newsgroups etc
I save the contents of this last file "outlook express" and then paste in other outlook programn . All my sent-received e-mail, pics in e-mail etc are here.
This may not be the best way of doing it but it works for me. I have every e-mail from last 3 years even through several disasters on computer.
