Question details

The user is unable to locate Microsoft Planner tasks that do not have assigned due dates, despite not having deleted them.

Product: Microsoft Planner
Device & OS: not provided
Scenario: Tracking and managing tasks and progress within a Microsoft Planner board.

Before you start

Ensure you are logged into your Microsoft 365 account with the correct credentials and verify that you are viewing the correct Planner board where the tasks were originally created.

Solution 1Recommended

Adjust Planner Filters to Reveal Hidden Tasks

Often, tasks aren't actually deleted but are temporarily hidden by active filters in your Planner view.

Microsoft Planner retains view settings that might filter out tasks lacking specific criteria. Checking your active filters is the quickest way to resolve missing tasks.

Open Microsoft Planner

Access the Filter Menu

Click on the 'Filter' option located in the top right corner of your active Planner board.

Clear Existing Filters

Click 'Clear' at the top of the filter dropdown to remove any active filters that might be hiding your tasks.

Select 'No Date' Option

Under the 'Due date' filter category, specifically check the 'No Date' option to force the board to display tasks without assigned deadlines.

Quick Tip: Also check the 'Progress' filter to ensure tasks aren't being hidden because they are marked as 'Completed' or 'Not started'.

Solution 2

Contact Your Microsoft 365 Administrator

If tasks remain missing after clearing filters, a backend investigation is required because Planner lacks a user-facing recycle bin.

Frequently Asked Questions

Does Microsoft Planner have a recycle bin for deleted tasks?

No, Microsoft Planner does not have a standard built-in recycle bin. If an individual task is deleted, it is permanently removed from the user interface and cannot be directly restored by the user.

Can a Microsoft 365 admin restore deleted Planner tasks?

While there is no user-facing recycle bin, Microsoft 365 administrators can sometimes recover entire deleted Plans by restoring the associated Microsoft 365 Group within a 30-day window. However, restoring individual deleted tasks requires the admin to open a specific backend service request with Microsoft support.

Why did my tasks without due dates suddenly disappear?

Tasks often disappear from view because a specific filter has been applied to the board. By default or by accident, tasks might be filtered out if the 'No Date' option is unchecked or if a 'Progress' filter is excluding them from your current view settings.

Is there a way to backup my Microsoft Planner tasks?

Currently, Planner does not offer a native one-click backup feature. Users often export their Planner boards to Microsoft Excel periodically (by clicking the three dots at the top of the plan and selecting 'Export plan to Excel') to keep an offline record of tasks, progress, and assignments.
