Browser-based settings don't always follow users across devices.

Collabora Online's Server-side Settings let admins manage shared configurations while users keep their own preferences.

Custom dictionaries, document themes, and more via a WOPI-based API.

@gakkoIT @SDIS57 Thanks so much for sharing your thoughts! 😍 We couldn't agree more. It's great to see this making a real difference!

[Collabora Office @CollaboraOffice]

Many of Moselle’s firefighters are volunteers: people with daily jobs who give their free time to relief missions. For them, a new tool can’t come with a training course.

When @SDIS57 (Sapeurs-Pompiers de la Moselle), the fire and rescue service of Moselle, replaced its ageing and complex file server with a new collaborative platform, @Arawa_fr, an open source integrator, deployed Collabora Online as its document editor.

The result: collaborative editing in open formats, with control over their own data. And thanks to a familiar interface, users got started with user guides instead of training.

AI in your office suite, without your documents leaving your infrastructure?

At the South Tyrol Free Software Conference (@SFScon) in Bolzano, Thorsten Behrens will show how Collabora Office integrates AI features such as writing assistance, formula troubleshooting, and slide creation, while keeping data under your control.

He’ll also look at local and self-hosted LLM integration patterns, the latency and quality trade-offs involved, and the governance questions that remain even with an open model.

📍NOI Techpark, Bolzano
🗓 14 Nov

Our VP of Sales and Business Development, Eloy Crespo, joins Manuel Voigt, Open Source Consultant at Adfinis, for a practical discussion on sovereign collaboration.

1. Click a colleague’s avatar and your view follows theirs, handy on review calls.
2. Every edit is tracked with author and time, in a colour per person.
3. Comments run in threads, and an @mention sends feedback straight to the right person.
4. When it’s time to share, add a password and an expiry date.

Thanks @LinuxNews_de for covering our statement on the Danish pilot: the F2 integration was completed, reported issues were resolved, and the pilot was interrupted by the elections and the ministry merger, not by technical difficulties. Work in Denmark continues.

New in our community interview series: Areg, who started contributing to #CollaboraOnline to challenge himself and learn in public.

His first patch replaced bitmap icons in the font selector with vector graphics. Today he works on interoperability and back-end fixes, including a recent Calc crash fix.

He also shares what he's learned from code reviews, and why your first contribution doesn't have to be intimidating.

Do you remember your first open source contribution? We'd love to hear about it!

@trumwill A bit of background: the Danish pilot was put on hold following a government reorganisation, before a formal evaluation could be completed, and the reported issues were resolved. Work with other Danish public authorities continues.

For context: the pilot’s first phase demonstrated that users could switch between Collabora Office and Microsoft Office within the same platform, using Microsoft-compatible formats. The pilot was later put on hold following a government reorganisation, before the planned evaluation could be completed.
