The new Collax Groupware Suite

Communication and Organization – Rethought: Secure, Flexible, and Independent

The new Collax Groupware Suite is a powerful alternative to Microsoft Exchange. With native, 100% Outlook compatibility (MAPI), it brings emails, calendars, contacts, and tasks together in one centralized and familiar environment. Ideal for small and medium-sized businesses, government agencies, and healthcare institutions with high demands for data protection, efficiency, and digital sovereignty.

Data Sovereignty Through Open Source

Especially relevant for IT managers and data protection officers: Collax consistently relies on open-source technology, ensuring organizations retain full control over their data – a crucial advantage in times of increasing demands for privacy and compliance (e.g., GDPR).

Unlike Microsoft, which increasingly pushes customers into the cloud while often outsourcing data without notice, all data with the Collax Groupware Suite stays securely within your organization. And you won’t miss out on any features – thanks to native Outlook compatibility (MAPI) and Exchange ActiveSync (EAS), your data is always accessible worldwide on all devices.

Central Platform for Email, Calendars, Tasks, and Contacts

The full-featured Collax Groupware Suite (CGS) empowers teams and organizations to collaborate efficiently – anytime, anywhere. It brings together all key functions of digital collaboration in one single platform:

🔹 Email communication
🔹 Calendar and appointment management (incl. group calendars, scheduling)
🔹 Contact management
🔹 Task and project management
🔹 File and document sharing
🔹 Notes and shared workspaces
🔹 Mobile and remote access

Whether it’s strategic independence for IT managers, cost savings for SMEs, or increased security for public institutions – the Collax Groupware Suite is the smart choice for anyone seeking more control over their digital communication. Now is the time to make the switch. The solution integrates easily into existing IT infrastructures – even in heterogeneous environments.
