The Microsoft Office 365 Enterprise license includes the use of three different versions of the Office software. Office can be installed on the computers and laptops of employees (Office 365 ProPlus), installed on smartphones and tablets (mobile Office apps for iOS and Android) and as online applications running in a browser (Office for the Web, previously known as Office Online). This Data Protection Impact Assessment (DPIA) is a repeated assessment of the use of the last two versions of the software: Office for the Web and the mobile Office apps. The Dutch government’s department managing strategic vendor relations with Microsoft (SLM Microsoft Rijk) has published the earlier DPIA on 23 July 2019.
