A feature-rich drop-in-replacement for Microsoft Exchange

Exchanging Exchange

Summary

Grommunio offers a fresh new start for open source groupware, and it serves as a real alternative for Microsoft Exchange. With its variety of certifications and compliance with a long list of regulations, customers with strong security and data protection needs will especially benefit from the switch. The version released in August brought certification from the German Federal Office for Information Security (Bundesamt für Sicherheit in der Informationstechnologie (BSI), which is somewhat similar to the US National Institute of Standards and Technology (NIST)).

Accessibility, according to WCAG 2.1 has been on board for some time, and there's more in the pipeline. According to the website, grommunio scales: The vendor claims to be faster than Exchange and more efficient than any other open source groupware. Seems like it's time for a test run.
