I have a friend who has a new computer and has asked me to move three Outlook email accounts data to the new machine. I know how to export to a .PST file and import the file, but in the past I have run into the situation that the mail was then duplicated when the ISP mail account was set up on the new install. All of the mail accounts are POP accounts. The new mail account I will set up will be IMAP, so no problem there. I think the users primary account will be a POP account. I will need to copy both received and sent mail as well as their contacts. Thanks for your help!
