In 2006, I was using Outlook 2003 in which I created a PST data file to store
my personal messages.

Then in 2007, I migrated to Outlook 2007 and added the old PST file via
Tools Options Mail Setup Data Files Add (Browsed for my PST). My
'Personal Folder' tree got restored fine, and I continued using this PST. I
also created several calendar entries, tasks and contacts painstakingly. I
took regular backups of this 700MB PST file.

Now in 2008, I do not have access to my old laptop and I have a new exchange
server to connect to (yes, switched my job). On the new laptop, I added the
old PST file via Tools Options Mail Setup Data Files Add (Browsed for
my PST) in Outlook 2007. In the 'Personal Folders' tree, I got all my mails
back. Also I can click on the ‘Calendar’ and ‘Tasks’ buttons and see the
appointments and tasks in the PST file. But the ‘Contacts’ button yields a
empty list.

If I go to address book, 'Global Address book' shows exchange server
contacts, but my personal contacts stored in the PST file are gone. 'Outlook
address book Contacts' entry is there but no contacts in there.

Can anybody tell me where my contacts have disappeared?
