You can try this. It does work. Unless you compacted your PST afterwards. (right-click on Personal Folder, Properties, Advanced, Compact now) Ever wondered why, when deleting items in your PST, the size doesn't get smaller? You first have to compact it. For corrupt DB's, I have used many tools, from the standard ScanPST.exe to Easy Recovery Pro's tool. Every single one of these tools I have lost the entries to the contacts list. All contacts view as standard emails, with all details and numbers, but the email address is gone. If you export this to CSV, even then you'll see the addresses are in none of the tables.
