I have a client that is still running outlook express with XP and on POP3 based e-mail. I've not played with Exchange or IMAP much but would it be possible to import all their addresses, folders, and emails from OE to a more modern email protocol? Right now I am upgrading one machine to Windows 7 with Outlook and trying to move their e-mail accounts and everything over is quite the nightmare.
The goal is to move their POP3 from their old provider to an account I set up over at SolidShellSecurity.com. They set up IMAP accounts for me just wasn't sure how to port their mail up so that it would sync over.
