In May 2019, the Dutch government has commissioned a new Data Protection Impact Assessment (DPIA) on the processing of data about the use of the Microsoft Office 365 ProPlus software. This DPIA assesses the progress with commitments made by Microsoft after the first DPIA, published in November 2018. This report provides a technical analysis of the data about the usage of the new Office 365 ProPlus software version 1905 released by Microsoft on 11 June 2019. In a separate DPIA simultaneously published with this report, the risks are analysed of the use of Office Online and the mobile Office apps.
