In Microsoft Exchange, the process of keeping public folders up to date is called public folder replication . The capabilities of public folders can then be utilized to replicate and control access to the information within an organization. Because data is stored in a public folder, it can be accessed using a newsreader, Web browser, or MAPI client such as Outlook. In addition, you can make a change on any server in a multiserver environment, and those changes are immediately and automatically replicated to all the other servers in the site.
Microsoft Exchange Server is a reliable, scalable, multiprotocol communications and collaboration server for the Internet and intranets . Running in combination with IIS, Exchange supports the HTTP, POP3, NNTP, SSL, and LDAP Internet standards. Exchange data is stored in a public folder, which makes it accessible using a newsreader, Web browser, or MAPI client such as Outlook. In addition, a change made on any server in a multiserver environment is immediately and automatically replicated to all the other servers in the site.
