Microsoft Flow is a service that helps automate workflows across various apps and services. It provides over 100 templates to get started quickly and connects to common systems through connectors. Users can build their own custom workflows with multiple steps, conditions, and connections to services like Exchange, Dropbox, SharePoint, mobile apps, IoT devices, and custom APIs. Flow is powered by Logic Apps and leverages the same runtime and visual designer while providing a simpler experience for typical office users. Administrators can manage Flow resources and set data policies from the admin center.
