There is out-dated information on some of these pages, specifically with
regard to Outlook 2003 and 2007.
The main points to note:
1. Do NOT use the import/export function to move Outlook data from one
version to another - all you need to do is to copy the pst file, with
Outlook closed.
2. Do NOT paste the copied pst file into the default location when restoring
from a backup - paste into (for example) your Documents folder and then do
File-Open-Outlook Data File within Outlook.
