- Switzerland’s federal government has launched a pilot program to test open-source alternatives to Microsoft 365 across around 3,000 government computers.
- The project centers on openDesk, an open-source workplace platform developed under Germany’s Centre for Digital Sovereignty, bundling tools for email, file storage, video calls, and document editing.
- Swiss authorities say the move is about gaining greater control over government data and reducing dependence on foreign technology providers.
Switzerland is making a bold move to cut its reliance on Microsoft. The federal government has launched a pilot program to test open-source alternatives to Microsoft 365. The test will run across roughly 3,000 government workstations. The goal is to give Switzerland more control over its own software, data, and digital systems.
The Swiss Federal Chancellery announced the program on September 2. It followed a feasibility study that found an open-source workplace could meet the government’s needs. Around 3,000 employees will gain access to the new system by the end of 2027. The first phase carries an estimated cost of CHF 9 million, according to Geoportal.
The Platform Switzerland is Betting On
The project builds on openDesk, an open-source workplace platform developed under Germany’s Centre for Digital Sovereignty (ZenDiS). OpenDesk bundles several tools that government workers use every day. Collabora Online handles document editing. Open-Xchange manages email and calendars. Nextcloud stores files. OpenProject tracks project work. Jitsi powers audio and video calls. Element handles chat. Univention manages user access and identity.
Together, these tools aim to cover the core functions that Microsoft 365 currently handles. That includes email, calendars, document editing, presentations, phone services, and video conferencing. Switzerland is not dropping Microsoft overnight. The new platform will run alongside Microsoft’s existing services during the pilot. That way, workers can test the new tools without disrupting daily government operations.
An earlier test involving 172 government employees helped shape the current program. According to Tecnoblog, the open-source platform performed well in areas like document handling, file storage, email, and calendars. Some limitations showed up in more advanced functions, but the overall results were positive enough to move forward.
Why Switzerland Wants Out of Microsoft’s Ecosystem
Digital independence sits at the heart of this project. Swiss authorities want to stop relying heavily on any single foreign technology company. They also want more freedom to decide how government data and digital systems get managed. Recent reporting flagged concerns that sensitive government information could potentially reach foreign authorities through software controlled by companies outside Switzerland, according to Windows Central.
Smart TVs can also pose surveillance risks. Former CIA officer John Kiriakou said the agency’s “Weeping Angel” tool could capture audio from smart TVs, even when switched off, highlighting broader security concerns around connected devices.
Switzerland is not the first government to look in this direction. Other countries and cities have explored similar moves. But the experience of others also shows how tough this kind of switch can be. A 2026 study by the City of Zurich and Bern University of Applied Sciences tested openDesk against real workplace demands.
The study found the platform could handle many basic tasks. However, it also flagged serious gaps around automation, phone systems, cybersecurity, and deep ties to existing IT setups. The researchers concluded that a full Microsoft 365 replacement was not yet possible for the city.
Munich’s well-known Linux experiment also serves as a reference point. That city tried to replace Microsoft systems years ago and ran into significant problems. Document compatibility, Excel macros, email systems, and user identity tools all created friction. Those challenges are not unique to Munich. They reflect how deeply Microsoft products embed themselves into government and business operations over time.
What the Results will Determine
The online reaction to Switzerland’s announcement has been mixed. Some people welcome the move as a smart step toward data control and independence from a single tech giant. Others point to past failures as a warning that swapping out deeply integrated Microsoft systems is far harder than it looks on paper.
Switzerland’s project is not framing itself as a complete exit from Microsoft. It is building a credible alternative, one that could grow over time if the results prove strong enough. The pilot data will help officials decide whether open-source workplace software can scale across the full federal administration. Security, compatibility, and day-to-day reliability will all factor into that decision.
The federal government has not set a firm deadline to replace Microsoft 365 entirely. The 2027 target only covers the initial rollout to 3,000 workers. Broader expansion will depend on what the pilot reveals. For now, Switzerland is watching carefully, testing quietly, and keeping its options open, according to reporting by ICT Journal and Frandroid.
