Question details

The user wants to enforce a strict view in Microsoft Lists where users can only see tasks assigned to them, preventing them from modifying the filter to view tasks assigned to others.

Product: Microsoft Lists
Device & OS: not provided
Scenario: Managing task visibility and permissions in a shared Microsoft List so that individuals are restricted to their own assigned tasks.
Observed behavior: Users can currently modify or remove the "Assigned To = [Me]" filter in the list view, allowing them to see tasks assigned to other team members.

Before you start

Before attempting to change list restrictions, ensure you have Site Owner or Full Control permissions to access the Advanced Settings of your Microsoft List.

Solution 1Recommended

Use Item-Level Permissions Based on Creator (Workaround)

While Microsoft Lists cannot natively restrict visibility based on the 'Assigned To' column, you can enforce item-level permissions so users only see items they created.

Microsoft Lists does not provide an out-of-the-box setting to permanently restrict users to items assigned to them. View filters like "Assigned To = [Me]" are purely for convenience and do not act as security boundaries. If users know how to change the view, they can bypass the filter.

As a built-in alternative, you can restrict users to only read and edit the items they originally created.

Open List Settings

Navigate to your Microsoft List, click the Gear icon (Settings) in the top right corner, and select 'List settings'.

Access Advanced Settings

Under the General Settings column, click on 'Advanced settings'.

Modify Item-Level Permissions

Locate the 'Item-level Permissions' section. Under 'Read access', change the selection from 'Read all items' to 'Read items that were created by the user'.

Save Changes

Scroll to the bottom of the page and click 'OK' to apply the new security rules. Users will now only see tasks they created, regardless of any view filters.

Important Limitation: This setting strictly applies to the 'Created By' field. It will not help if a manager creates the tasks and assigns them to different users, as the manager would be the creator.

Submit a Feature Request

Request official support for 'Assigned To' item-level security directly from Microsoft.

Frequently Asked Questions

Can I hide specific columns in Microsoft Lists from certain users?

No, column-level security is not available out-of-the-box in Microsoft Lists or SharePoint. While you can hide columns in a specific view, any user with access to the list can create a personal view or modify the current view to reveal hidden columns.

Is the [Me] filter considered a security feature?

No. The [Me] filter dynamically adjusts the view to show items related to the logged-in user, but it is strictly a convenience feature for filtering data. It does not alter the underlying permissions, meaning users can simply clear the filter to see all data.

Can Power Automate enforce item-level permissions for assigned tasks?

Yes, as an advanced workaround, you can build a Power Automate flow that triggers when an item is created or modified. The flow can automatically break permission inheritance for that specific list item and grant exclusive Read/Edit access only to the user specified in the 'Assigned To' column.
