We offer practical trainings and workshops for administrators, IT teams, and organizations that want to operate and further develop their infrastructure efficiently. Our sessions combine in-depth technical knowledge with hands-on exercises, enabling participants to apply what they learn directly in their daily work.

A particular focus is on grommunio, the modern open-source groupware platform for email, calendars, contacts, and collaboration. In our trainings, you will learn how to securely install, configure, and operate grommunio efficiently.

Our trainings cover topics including:

• Installation and deployment of grommunio
• Administration and user management
• Migration from existing mail systems (e.g., Exchange)
• Security, backup, and high availability
• Troubleshooting and operational best practices

Workshops can be conducted remotely or on-site and are tailored to your infrastructure, experience level, and specific requirements.
