What Microsoft 365 collaboration and productivity services are discussed in MS-900?

MS-900 includes a module dedicated to Microsoft 365 productivity and teamwork capabilities. The intent is to provide a baseline view of the collaboration and productivity service areas that organizations typically adopt early when moving to Microsoft 365.The module lists Microsoft 365 productivity and teamwork solutions as a starting point. It then calls out several services and capability themes. Collaboration and engagement are referenced through Microsoft Stream, Teams, and Yammer, which are positioned as tools that support communication and engagement patterns across employees.Productivity across endpoints is included through Office across all devices. This is presented as part of the broader productivity suite and helps learners understand that Microsoft 365 is not limited to a single device type or working location. It supports the SaaS framing of accessing services consistently across user contexts.File storage and sharing is explicitly covered. The module lists OneDrive and SharePoint for file storage and sharing, which are foundational services for content management, collaboration, and information access in many Microsoft 365 deployments.In practice, this module helps learners identify what the primary collaboration surfaces are within Microsoft 365 and how those surfaces relate to everyday work. It also sets up later conversations about security and compliance, because collaboration tools and file services are central to information protection and governance requirements.
