Dutch tax authority will ditch Microsoft 365 in favor of on-premises and open source

Neowin reports that the Dutch tax authority, the Belastingdienst, is halting its move to Microsoft 365 and will instead run Microsoft email and calendar services on its own servers next year while it looks for European options for storage and collaboration. The agency is trying to reduce its reliance on Microsoft without cutting the company off entirely, and will keep using tools such as Outlook, after earlier Dutch reporting said the rollout had been paused over a critical report and a EUR 14.4 million bill for the original migration.
