Rivka,

It depends on what version of Outlook you have and whether your company runs Microsoft Exchange Server. With an Exchange server you can share info very easily. Without Exchange there are also ways to share but some are a bit clunky. IIRC, for versions of Outlook prior to Outlook 2000, you definitely need either Exchange or some third party plugin. I think there are ways to make Public folders without Exchange in all versions of Outlook from 2000 on.

Our office upgraded from Outlook 98 to 2003 with Exchange Server in March and most people in my office still have no idea how to use the public folders I set up (not for lack of trying to teach them confused ), but those who do use the sharing and public folders really like it.
