If you connected via a POP connection, your email will be located in a .PST folder. If you were still using Vista on the previous drive, that folder should be located in the following location:

c:\Users\[username]\AppData\Local\Microsoft\Office

You may have multiple .PST files, depending on if you archived, or if you set up multiple email accounts or profiles. You may want to open each .PST in Outlook first to make sure you have the right file. You can do that but just going to the File menu in Outlook and selection Open. Once you have the right file, just import it using the Import wizard (File > Import and Export).

Hope this helps.
