Outlook stores all information in PST files.... Mine for example are:

in data file C:\Users\Steve\...\Microsoft\Outlook\[email protected](3).pst

The short version is to get the PST file(s) to the new drive/safe location.... And then inside Outlook click on File-> Open -> IMPORT-> Import from another program or file. (this method assumes that Outlook is up and running)

Or...during setup of Outlook, you can point the setup to the PST files and it will continue to use it/them. (you'd want to copy the PST files to the C:\Users\Steve\...\Microsoft\Outlook location)

There are TONS of articles on doing this.....
