Hi,
If you upgraded from Outlook 97, it's very possible that your addresses are stored in a Personal Address Book (.PAB file). If you find that your email and calendar items are still there,
then you should seach your entire hard drive for all *.PAB files. Once you locate the Outlook .PAB file, you can then import it back into Outlook be referring to the following Knowledge
Base article.
