Grommunio

grommunio is an Austrian-developed open-source groupware platform designed as a direct alternative to Microsoft Exchange. It gives your organization full control over its communication and collaboration data, allowing for on-premise or private cloud hosting to meet strict data sovereignty and GDPR requirements. You decide where your data resides, not a third-party provider.

It provides a complete suite of tools to manage your team's daily workflow, including:

• Email, Calendars, Contacts & Tasks: Natively syncs with Microsoft Outlook (MAPI/HTTP) and mobile devices via Active Sync.
• Real-time Communication: Integrated video conferencing with grommunio Meet and persistent team chat.
• Document Collaboration: Securely share files and edit documents with a built-in office suite.
• Device Security: Manage and secure mobile devices with integrated Mobile Device Management (MDM), allowing you to wipe data remotely if a device is lost.

Built on a Linux foundation, grommunio offers a scalable and secure environment for businesses that prioritize digital independence and open standards.
