Microsoft Exchange Server - license & software assurance - 1 server

Microsoft Exchange Server is the e-mail server with integrated groupware that makes it easier to communicate. It combines electronic mail, group scheduling, electronic forms, and groupware applications on a single platform that you can manage with a centralized administration program. It is the most reliable way to send e-mail and access groupware applications over the Internet or any other network.

Microsoft Exchange Server provides reliable message delivery with tools that track if your message reached its destination and if it was read. Support for digital encryption and signatures lets you secure messages against unauthorized access and ensures that messages reach recipients unmodified. You can send and receive your e-mail by connecting to an Internet Service Provider from any location with Exchange. Exchange Internet Mail Connector provides fast multi-threaded connectivity. MIME is supported for sending and receiving messages with rich attachments. Automate your business processes with built-in groupware applications, over LAN or Internet. Share information more efficiently throughout your organization by posting it on easy-to-access bulletin boards and in tracking applications.
