How to access old email from XP Outlook 2003

I need to restore, copy, bring over, what ever you want to call it, but I need access to all of my personal folders and email that was left on my computer when I changed over to Windows 7. I successfully completed a Windows 7 Clean install after backing up my hard drive on to an external 250 gig flash (G). I also know and found that Windows 7 created a “Windows old” file on my hard drive, that also houses my Outlook 2003 backup (As I use the PST Backup utility).
I thought I could just copy the outlook file, rename the file (OutlookXPEmail) and place it in the Windows 7 Outlook file. See attached. But what do I do now? I am still running Outlook 2003, the same program that I was using when I was running XP. Can anyone help me?

Click of and the Outlook stops working and I get the following message



Now what ??
