Swiss public sector plans to phase out Microsoft 365 Office suite, launches migration pilot project

📅 2026-09-08

Abstract:

In order to reduce over-reliance on large multinational technology companies and enhance digital autonomy at the national level, the Swiss public administration has officially launched a key pilot project, planning to phase out the Microsoft 365 office suite and explore a comprehensive migration to a localized, open source and more controlled office collaboration software ecosystem.

The migration plan is spearheaded by the Swiss federal and regional technical authorities for public administration. For a long time, multi-level government departments and public institutions in Switzerland have relied heavily on Microsoft 365 cloud collaboration services with Microsoft Word, Excel, PowerPoint, Outlook and Teams as the core. However, as cloud services bring increased cross-border data flow risks, and as the global geopolitical and data compliance environment becomes increasingly complex, Swiss regulators have expressed deep concerns about public sensitive data being locked by external cloud service providers, potential data outflow risks, and long-term high commercial licensing expenses.

The pilot project launched this time mainly focuses on verifying the feasibility, safety and collaborative efficiency of alternative solutions in actual government work. According to the technology roadmap, Swiss officials are focusing on investigating modern office suites based on open source technology, including a privatized document sharing and collaboration platform based on Nextcloud, mature open source desktop editing tools such as LibreOffice, and secure email and instant messaging systems compatible with modern network protocols. The pilot is designed to test whether these alternative tools can perfectly replace Microsoft Teams' complex workflows such as audio and video conferencing, real-time online multi-person collaboration on documents, and calendar synchronization without affecting cross-department collaboration efficiency.

In addition to rigorous technical functional testing, data sovereignty and compliance are the core driving forces of this pilot. Switzerland is known for its strict banking secrecy tradition and data privacy laws. Officials clearly require that systems used to carry public management and citizen privacy data in the future must be deployed in Swiss local data centers or infrastructure with fully autonomous and controllable permissions to eliminate the long-arm jurisdiction risks that third-party foreign legal jurisdictions may pose to local data.

At present, the first batch of government departments and public officials participating in the pilot have begun to trial the alternative office platform in phases. The technical team will conduct a comprehensive assessment of the stability of the software, the difficulty of transitioning user operating habits, the two-way compatibility of old format documents, and the overall system operation and maintenance costs. Relevant Swiss authorities stated that although unbundling from the deeply bound Microsoft ecosystem is a systematic project that takes a long time and faces resistance from user habits, the launch of this pilot project demonstrates Switzerland's strategic determination to firmly promote digital self-reliance and build a diversified open software supply chain. If the results of the pilot evaluation are as expected, Switzerland is expected to promote this desoftening migration program to a wider range of federal agencies and even the public education system in the next few years.
