In a significant stride towards revolutionizing the email server landscape, grommunio proudly announces the launch of its latest version, 2023.11.3, marking a milestone in the domain of open-source communication platforms. This update heralds the full-scale integration of Exchange Web Services (EWS), now fully supported to run with Microsoft Outlook for Mac and Apple’s native organization apps, including Mail and Calendar. With this release, grommunio cements its position as the world’s first open-source EWS server, offering an unparalleled email and collaboration solution to businesses and individuals globally.

EWS: At the Heart of Collaboration
The highlight of version 2023.11.3 is the enhanced EWS compatibility, now exiting the beta stage and enabled by default. This advancement signifies a leap in interoperability with Microsoft Outlook for Mac and Apple’s ecosystem, facilitating a seamless and integrated experience for users across different device classes. The update ensures flawless synchronization and communication, fostering productivity and streamlined workflows.

Enhanced Security and Internationalization
Security and compliance receive a boost with updated S/MIME protocols for cross-device validation, ensuring secure and authenticated email exchanges. Additionally, the introduction of support for IDN (internationalized) domains in the Global Address Lists (GAL) broadens the accessibility of grommunio, making it a truly global platform that accommodates diverse linguistic and regional needs.

Improved Calendaring and Authentication
CalDAV’s newfound support for iCalendar’s free/busy information enhances scheduling and planning capabilities, while the integration of Passkey authentication with grommunio Auth introduces a cutting-edge, passwordless security feature, streamlining access without compromising on safety.

grommunio Web has received a series of polishing fixes, building on the last major design upgrade to offer a more intuitive and aesthetically pleasing user interface. These improvements aim to enhance user engagement and satisfaction, making email management a more streamlined and visually appealing experience.

Comprehensive Documentation and New Technologies
Acknowledging the importance of support and guidance, grommunio has undertaken a major documentation overhaul, providing users with extensive updates and clear, concise information to maximize the platform’s benefits.
