Dutch Tax Authority Halts Microsoft 365 Cloud Migration, Shifts to On-Premises and Open Source
Key points
- Dutch tax authority stopped Microsoft 365 cloud migration.
- Decision driven by digital sovereignty concerns.
- Will implement on-premises mail/calendar by 2027.
- European open-source solutions for storage/collaboration planned for 2027-2028.
Microsoft 365 Cloud Rollout Halted
The Netherlands' Tax and Customs Administration has abandoned its planned migration to Microsoft 365 public cloud. The rollout was initially scheduled for completion by the end of 2026, with approximately 5,000 employees already migrated before the decision to reverse course.
Focus on Digital Sovereignty
This reversal is attributed to a growing emphasis on digital sovereignty within Europe. A Linux Foundation report, released at Open Source Summit Europe, indicated that 94% of EU organizations consider digital sovereignty important, with 61% deeming it very important. This sentiment is a key factor in the shift away from proprietary cloud solutions.
Other European entities, including the Swiss military and various German agencies, have also moved towards Linux and open-source alternatives like openDesk, demonstrating a broader trend.
Transition to On-Premises and Open Source
The Dutch government will now pursue an on-premises and open-source strategy. State Secretary for Finance Eelco Eerenberg outlined a timetable for this transition. Mail and calendar provisions are slated to be realized on-premises by 2027.
Following this, European open-source solutions for personal storage and collaboration are planned for implementation in late 2027 and 2028. The existing Microsoft software will be retained for the interim period.
