How to Assign Multiple Due Dates to Planner Checklist Items

Product: Microsoft Planner
Device & OS: not provided
Scenario: Tracking complex tasks and project milestones where sub-tasks require independent deadlines.

Before you start

Verify your Microsoft 365 permissions to ensure you have the necessary access to create new Planner buckets, labels, or utilize Power Automate for custom workflows.

Create Separate Planner Tasks for Each Milestone

Since checklist items cannot have their own due dates, converting major sub-tasks into individual tasks is the most straightforward native workaround.

Microsoft Planner treats a task as a single deliverable. If a task has multiple phases requiring strict deadlines, breaking them down into separate tasks allows you to utilize Planner's built-in due date and reminder functions effectively.

Create new individual tasks

Instead of adding checklist items, click 'Add task' to create a distinct task for each project milestone or sub-step.

Assign independent due dates

Click on each newly created task and use the 'Due date' calendar picker to set the specific deadline for that milestone.

Group related tasks visually

Apply a common colored label to all tasks belonging to the same project phase, or create a specific 'Bucket' to group these milestone tasks together.

Use naming conventions

Adopt a standardized naming format, such as '[Project Name] - Phase 1', to clearly indicate that these tasks are linked parts of a larger objective.

Frequently Asked Questions

Can I set reminders for individual checklist items in Microsoft Planner?

No, Planner currently only sends notifications and email reminders based on the task's primary due date. Checklist items do not trigger independent reminders or notifications.

Will Microsoft add native support for multiple due dates in Planner?

Microsoft has not officially announced native support for multiple due dates within a single task. Users facing this limitation are encouraged to submit feature requests via the official Microsoft Feedback portal.

How can I easily view all my separated milestone tasks at once?

In your Planner board, switch the 'Group by' view located in the top right corner to 'Labels' or 'Buckets'. This allows you to see all separated tasks organized by the categories you created to link them together.
