Hi there! Great use case — Power Automate is exactly the right tool for this now that the native Planner calendar sync has been removed.
How to set it up
Use the Planner connector trigger + Office 365 Outlook connector action:
Step 1 — Trigger: "When a new task is created" (Planner connector)
- Select your Group and Plan
- This fires whenever a new Planner task is added
Step 2 — Action: "Create event (V4)" (Office 365 Outlook connector)
Map fields like this:
- Subject → Title (from Planner trigger output)
- Start time → Due Date Time (from Planner trigger)
- End time → Due Date Time (same, or wrap with addHours(..., 1) for a 1-hour block)
- Calendar Id → select your Outlook calendar (e.g., "Calendar")
- Optionally set Body → Notes from the task
Important note: The Planner connector supports basic plans only and does not have a "When a task is updated" trigger — only "When a new task is created", "When a task is assigned to me", and "When a task is completed". This means due date changes on existing tasks won't automatically update the calendar event. If you need that coverage, you'd need a second flow triggered on task completion to update/delete the original event.
