Microsoft > Exchange
Microsoft Exchange has proven to be a valuable product for businesses large and small since became available to the public in 1996. Exchange serves as a calendaring and mail server and has its roots as the mail client for Microsoft corporate headquarters. In the early days, Exchange exclusively used the proprietary protocol MAPI. After Exchange became available for use outside the walls of Microsoft, support for POP3, IMAP and SMTP was added.
