Exchange-Client License 5.5 (5-user) Competitive Upgrade [Old Version]

This package is a license (software must be purchased separately) that enables you to upgrade CALs from Microsoft Mail or any competitor product to Exchange Server 5.5. It includes five Client Access Licenses (CALs).

Microsoft Exchange Server 5.5 is a messaging platform that includes the tools that are necessary to create rich collaboration applications. It allows you to choose protocols and clients that are best for your company, instead of locking you into a single protocol environment. The Internet protocols are part of the core server architecture. It's designed to be easy to manage and administer, and to have tight integration with the operating system that shares a security context.

This version offers improved messaging connection and directory synchronization between:

• Microsoft Exchange and Lotus Notes 3 and 4, and Domino 4.x
• Microsoft Exchange Server and IBM OfficeVision/VM (PROFS)
• Microsoft Exchange and SNADS-compliant messaging systems
