Dutch Tax Authority Moves Away from Microsoft Office 365
The article reports that the Dutch tax authority (Belastingdienst) is moving away from Microsoft Office 365 due to concerns over data privacy and sovereignty. The decision follows an assessment that Microsoft's cloud services do not fully comply with EU data protection regulations, particularly regarding the transfer of personal data to the US. The authority plans to migrate to an alternative office suite that ensures data residency within the EU. This move reflects a broader trend among European public sector organizations seeking to reduce reliance on US-based cloud providers and enhance data protection. However, the full article is behind a paywall, so specific details on the timeline, alternative chosen, and implementation steps are not available. The initiative is part of the Dutch government's commitment to digital sovereignty and privacy compliance.
The move by the Dutch tax authority reflects a growing trend of European public sector entities seeking data sovereignty and reducing reliance on US cloud providers, which could influence other public sector decisions and impact Microsoft's cloud business in Europe.

Europe Moves to Ditch U.S. Software for Sovereign Tech
European governments and institutions are accelerating efforts to reduce dependence on U.S. technology, driven by data‑sovereignty and legal concerns such as the U.S. CLOUD Act. France is shifting major public systems — including its Health Data Hub — away from Microsoft Azure toward domestic providers like Scaleway, and the European Commission awarded a €180 million sovereign cloud tender to four European providers. Critics note persistent technical and commercial dependencies (for example, search engines relying on Bing or joint ventures using Google Cloud technologies). Private-sector buyers often still choose U.S. solutions, but policymakers hope procurement and public contracts will bolster Europe‑based cloud, AI and infrastructure alternatives.
Netherlands Builds Own Linux for Government
The Dutch government is developing DAWO (Digitaal Autonome Werkomgeving Overheid), a sovereign, open-source digital workplace for its public administration, based on the NixOS Linux distribution. This initiative, led by the Ministry of the Interior and implemented by state IT providers SSC-ICT, DICTU, and DUO-ICT, aims to reduce dependency on US tech giants like Microsoft. The trigger was Microsoft cutting the email account of ICC Chief Prosecutor Karim Khan due to US sanctions, highlighting the risks of relying on foreign tech. Eight municipalities are testing the system, which includes Nextcloud, Collabora, Element, and OpenProject under the 'MijnBureau' suite. A stable version is expected next year, with challenges in migrating legacy applications, ensuring MS Office compatibility, training staff, and ensuring long-term maintenance. Similar open-source initiatives exist in Denmark, France, Switzerland, and the German state of Schleswig-Holstein.
Office EU Launches as European Microsoft 365 Alternative
The first stable release of the open-source Euro-Office platform has been published. Project partners Nextcloud and Ionos announced the milestone; Office EU is one of the participating suites positioning itself as a European alternative to Microsoft 365 and Google Workspace. The suite bundles document, spreadsheet, presentation, email, calendar, cloud storage and videoconferencing apps (branded EU Docs, EU Spreadsheet, EU Presentation, EU Drive, EU Email, EU Calendar, EU Talk) and emphasizes operation on European infrastructure, open-source code and GDPR compliance to keep data within European legal jurisdiction. Other participating projects include XWiki, OpenProject and Open-Xchange. The launch is framed within the EU’s Technological Sovereignty Plan to reduce dependence on US tech providers, though analysts note such projects are unlikely to take large market share quickly.
