Denmark’s Ministry of Digitalization Ends Open-Source Office Suite Replacement Pilot

Denmark’s Ministry of Digitalization (Ministry of Digitalization / Digitaliseringsministeriet) has ended the pilot to replace Microsoft Office with the open-source office suite Collabora, with no plan to restart it and without completing the originally planned evaluation. The pilot started in the summer of 2025, involved about 38 to 40 employees, was delivered through Danish supplier cBrain, and was tested integrated into the case-handling system F2.

During testing, employees reported issues including document formatting and styling being scrambled, blank page errors, and difficulty tracking revisions, involving interoperability with Microsoft OOXML format. The pilot was suspended around the time of the election in early 2026; a ministry spokesperson confirmed it will not resume, and no systematic comparative evaluation was carried out. The ministry continues to use Microsoft Office and did not issue a formal announcement ending the pilot.

ABAB AI Insight

This pilot was a limited test promoted by Denmark’s Ministry of Digitalization in the context of pushing “digital sovereignty” in 2025 and reducing dependence on U.S. technology, with then Digitalization Minister Caroline Stage Olsen driving it and aiming to reduce use of Microsoft Office. The actual scope was limited to about 40 employees, and Collabora was integrated into the existing case system F2 through cBrain rather than replacing the entire ministry.

The document interoperability problems centered on conversion between Microsoft’s proprietary OOXML format and the open-source ODF format, showing up as formatting problems, blank pages, and broken revision tracking. Such problems are common in public-sector migrations because many legacy documents, templates, and external collaborations still depend on Microsoft formats. The ministry did not complete the originally planned comparative evaluation, so the severity of the technical problems and their causal link to the decision to end the pilot cannot be directly confirmed from the public material.

Compared with the public plan in June 2025, this ended quietly, without a formal announcement. Collabora reportedly said the pilot was paused because of the election and ministry changes and could possibly restart, but Danish media reports and the ministry spokesperson described it as ended with no plan to restart. Some Danish municipalities and other European public institutions are still exploring open-source alternatives, but this ministry-level pilot did not produce a replicable path.

The result leaves the ministry continuing to rely on Microsoft Office, and the limited pilot did not expand into a larger migration. The practical usability of open-source office suites in government settings still depends on compatibility with existing proprietary formats and business processes, rather than on software licensing or sovereignty statements alone.

  1. The end of a limited employee pilot with no evaluation does not mean a conclusion has been reached on the overall viability of open-source solutions.

  2. Compatibility problems with proprietary document formats make replacement tests in the public sector difficult to sustain within existing workflows.
