Note

  • An active task is a task that is not completed.
  • Delta sync lets users passively receive updates in real-time while the app is open. Users beyond the delta-sync limits will not see updates in real-time.
  • Most Planner plans are owned by a group. Plans created by other apps, and shown in Planner, may be owned by a user.
  • A context is the association between a plan and a host container like a Teams tab. The limit on contexts is a limit on how many associations a plan can have.
