Good! You should never import native Outlook data. Why?

Importing an entire PST may well corrupt your profile and may create a
ghost
PST that you can't close. Importing PST's will lose:
1. Custom Forms
2. Custom Views
3. Connections between contacts and activities
4. Received dates on mail
5. Birthdays and anniversaries in calendar
6. Journal connections
7. Distribution Lists
Opening a PST file will preserve all of these. That is why we do not
advise
people to import a native file into Outlook.
As to your problem, first make sure that the file has any read-Only
attribute removed, then in Outlook do File-Open-Outlook Data File and
navigate to where you copied it to. If you still get "Access denied" then
I would presume it's a Vista permissions problem, which unfortunately I
know nothing about!
