Microsoft 365 is the default in many organisations, and defaults rarely get questioned. Until a licence renewal or a data sovereignty review brings the decision back to the table. If you’re considering an open source alternative that runs on your own infrastructure, our white paper offers a side-by-side feature comparison of Collabora Online with Microsoft 365.

Integrators: set up your editor once to work the same across all your devices, or the entire organisation. Server-side Settings in Collabora Online make this possible for integrators. Through a WOPI-based Settings API, settings are stored on your WOPI host, and sync across devices. ⚙️ For admins, that means one place to roll out custom dictionaries, AutoText and document themes for the whole organisation. 💻️ For users, it means interface preferences, AI assistant, document signing and Zotero credentials get set up once, and are available everywhere. Our new blog walks integrators through how it works across all the customisable settings categories, step by step. Get customising: 🎨 buff.ly/ibT98Xb #CollaboraOnline #OpenSource #WOPI

If you can't run it on your own servers, it's hard to call it sovereign. Digital sovereignty is decided in practice: whether you can inspect your software, deploy it where you choose, and keep your documents in open formats you control. Collabora Online is built from clean Open Source, and around the Open Document Format (ODF). It's built by a European company with engineers across 27 countries and more than 500 community contributors, so the support you get comes from the people who maintain the code. Here are six reasons organisations choose Collabora Online as their sovereign office suite, from deployment freedom and open standards to where security is actually enforced. 🔗 buff.ly/euw031F #CollaboraOnline #OpenSource

Open source won the server. Can it win the workplace? In this episode of the Open Matters podcast, Gerald Pfeifer, former CTO of @SUSE and now part of Open Productivity, shares his perspective on the future of open-source productivity. From Linux and Kubernetes to digital sovereignty and the growing importance of browser-based collaboration, the conversation explores what it takes to bring open source into the workplace. Tune in to hear why Gerald sees Collabora Online as an important part of that journey, and how Open Productivity aims to bring openDesk (@[email protected]) to more organisations. ▶️ Watch the full episode: buff.ly/u2KfhJt #OpenSource #DigitalSovereignty #CollaboraOnline #openDesk

❌️ Microsoft ends support for Office Online Server on 31 December 2026 ❌️ After that date, in-browser editing of documents stored in on-premise SharePoint is no longer supported, and the usual advice is to move everything into Microsoft's cloud. For organisations that keep documents on their own infrastructure, that isn't an option. Collabora Online is an open-source, self-hosted collaborative office suite that runs on your servers, in your network, and integrates with your existing document storage, so documents never leave your infrastructure. See how to keep browser-based document editing in SharePoint with Collabora Online. ▶️ buff.ly/9UDYKkW #SharePoint #OfficeOnlineServer #CollaboraOnline #SelfHosted #OpenSource #DigitalSovereignty
