How to Automatically Assign Tasks to a Specific User in Microsoft Planner

Product: Microsoft Planner
Device & OS: not provided
Scenario: Creating new tasks in Microsoft Planner where assignment needs to be routed based on specific criteria like buckets or requests.
Observed behavior: Planner does not automatically assign tasks based on properties, requiring manual assignment or defaulting to the creator.

Before you start

Ensure you have access to Microsoft Power Automate with your Microsoft 365 account, as Planner requires a custom automated flow to handle conditional assignments.

Create a Power Automate Flow for Task Assignment

Use Microsoft Power Automate to detect when a new task is created and automatically assign it based on specific bucket or request conditions.

Microsoft Planner does not have a built-in feature to automatically route tasks to specific users. To achieve this, you must rely on Microsoft Power Automate to set up trigger-based rules.

Start a New Flow

Configure the Planner Trigger

Choose the trigger 'When a new task is created' under the Microsoft Planner connector, then select your specific Group and Plan from the dropdown lists.

Add Routing Conditions

Click 'New step' and add a 'Condition' control. Set the parameters to evaluate task properties, such as checking if the 'Bucket Id' or task title matches specific text.

Update the Task with the Assignee

In the 'If yes' branch of your condition, add the 'Update a task' action from the Planner connector. Provide the Task ID from the dynamic content.

Assign the Specific User

In the 'Assigned User Ids' field, enter the specific email address or user ID of the person you want to route the task to. Save and test your flow.

Frequently Asked Questions

Can I assign a Planner task to multiple users automatically?

Yes. Within your Power Automate flow, you can assign the task to multiple users by inputting their respective email addresses, separated by semicolons, in the 'Assigned User Ids' field.

Does Planner have native auto-assignment rules without Power Automate?

No, Microsoft Planner currently lacks built-in rule-based task routing. All automatic assignments based on task details must be handled via Power Automate integrations.

How do I find the Bucket ID for my Power Automate condition?

You can find the Bucket ID by adding a 'List buckets' action in Power Automate or by checking the execution history of your Planner trigger to view the raw output IDs.

Why is the task creator assigned by default?

By default, Planner may leave tasks unassigned or default to the creator depending on the environment where the task was generated. Power Automate overrides this default state by immediately updating the assignee once the task hits the board.
