To update the status or change assignments, just drag and drop tasks between columns. -- Visibility -- The My Tasks view provides a comprehensive list of all your tasks and their status across all your plans. When working together on a plan, team members always know who is working on what. -- Collaborate -- Built for Office 365, Planner lets you work together on the same tasks, attach captured photos directly to them, and even have conversations around tasks without switching between apps.
