Copying oulook pst file from a back up after reinstalling Office 2

[Anand]

When I try to Add an Outlook pst file from a back up I get a message
Outlook.pst is not a personal folder file and does not allow me to access all
my old mails and contacts. I had to reinstall XP and subsequently Office 2007.

If the backup is on a cd you cannot do it from there.
Copy pst to eg Documents folder, in explorer check properties of pst to
ensure read only is off.
Then in OL, File>Open>Data File........browse to its location

If you still get an err msg then likely the method of creating the backup
failed
