Sharing Outlook Folders w/o Exchange

How do I share Outlook 2000 or 2002 calendars and/or contacts without having an Exchange server? I know it can be done, but can’t find the documentation. Don’t want to just send invitations to meetings for calendar sharing… When I click on File, Share, it asks for the CD, which I do, but the sharing still doesn’t work – says I need an Exchange Server – not an option at this site. Isn’t there a way to send others/or share your calendar? Also, with contacts – don’t want to just send .vcf’s; want to actually share. If you can help, you’re my heros! Thanks, Susan B.
