Netherlands
Office.eu is run by EUfforic Europe BV, a Dutch company based in The Hague that launched the service publicly in 2026. Office.eu puts mail, calendar, contacts, file storage and collaborative documents into one account that sits entirely under European ownership and EU data rules.
The platform is built on Nextcloud Hub, with document editing handled by the open-source Euro-Office engine, so nothing is locked into a proprietary format you cannot take with you. Office.eu is a founding member of the Euro-Office alliance alongside Nextcloud, IONOS, OpenProject and others, which is working towards a shared, exportable office standard for Europe. If you want a straight replacement for Microsoft 365 or Google Workspace rather than a single app, this is the most direct like-for-like option on the list.
