I am using Outlook 2007 as a client and Exchange 2003 as an e-mail system and
I am unable to share personal contact list or Calendars. Both clients are
Office 2007 and we are receiving the sharing notification emails. When you
try to open the email you receive an Outlook message stating that you cannot
open the message. If you receive a request to share your resource, the Allow
and Deny respond buttons are disabled.

What happens if you try the File | Open | Other User's Folder command?
