Open-Xchange is a modern groupware based on Linux, and is a practical alternative to Microsoft Exchange. An open-source exchange server as part of a 1&1 business email package
enables you and your entire team to access company documents anytime, anywhere. Calendar and contact details can be retrieved and edited by all authorised employees; giving you complete control over user and group administration. Practical tools for managing tasks and projects, data exchange in a matter of seconds and a shared, up-to-date database enables you to streamline business operations and simplify internal communication. As such, open exchange helps you to optimise the processes used within your company or institution.
