A type of recipient in Microsoft Exchange Server that can store messages and documents for sharing with other users in an Exchange organization. Public folders can contain simple messages, attachments, multimedia clips, binaries, and any other type of file. They can also contain custom forms that facilitate contributing and viewing information.
To create public folders in an Exchange organization, you should use the client program Microsoft Outlook. Public folders created with Outlook can later be configured using the Exchange Administrator program, which you cannot use to create public folders.
