Microsoft violates the GDPR on a massive scale

20. November 2018

A Data Protection Impact Assessment (DPIA) outsourced by the Dutch Ministry of Justice and Security, concluded that Microsoft collects and stores personal data of Office users on a large scale without informing them. According to this report, Microsoft thus violates the General Data Protection Regulation (GDPR) on a massive scale.

The DPIA was carried out to probe the use of Microsoft Office in the public sector. Most of the Dutch authorities use Microsoft Office 2016, Office 365 or an older version. The Dutch judiciary, police, various ministries and tax offices use Word, Excel, Outlook and PowerPoint. The DPIA found that Microsoft not only collects and stores personal data but also send them to the US. In addition, users are not informed and it is not offered to switch off the collection or to see what data are collected. The Assessment outlined eight different risks and possible risk mitigating measures. One example is the “Lack of Transparency”. A possible measure recommended for Microsoft is the public documentation and the implementation of a data viewer tool because at the moment the content of the diagnostic data (i.e. “all observations stored in event logs about the behaviour of individual users of the services”) is not accessible.

Microsoft stated that -for the examined Office versions- between 23,000 and 25,000 event logs are sent to Microsoft servers and that 20 to 30 development teams analyse the data. The company agreed to change its practices by April 2019 and until then offers “zero exhaust” settings to shut down the data collection. A Microsoft spokesperson told The Register: “We are committed to our customers’ privacy, putting them in control of their data and ensuring that Office ProPlus and other Microsoft products and services comply with GDPR and other applicable laws.”

In addition to applying the new settings, the DPIA encourages users to deactivate Connected Services and Microsoft’s data sharing system, not use the web-based Office 365, SharePoint, or OneDrive, delete the directory of the system, and consider using alternative software.
