I am using Windows XP and Outlook 2003. I need to back up a laptop in case of a hard disk crash. What files do I need to backup (for Outlook) in order to ensure I don't lose anything (contacts, email messages, calendar entries, etc). I need to be able to restore it completely. I know you can export each thing separately and I also see a .pst file but it is huge. Also, what does "purging" old items mean? Are they still kept somewhere? How can I get the .pst file smaller if that is what I need to backup?
Thank you for any help,
