Corporate Exchange Contacts Won't Sync

I have a corporate OTA MS-Exchange email account that syncs all emails, contacts and calendar events with my iPhone. When I try to sync to my personal PC, 99% of the contacts do not sync. Why?

I recently changed companies. The old company shut off my exchange account access and these same 99% of contacts, most of them personal instead of business, are now no longer viewable on the iPhone. How can I view them again to either manually capture the data or send them to my new exchange sync account?
