Question details

The user wants to configure Microsoft Lists so that all specialists can view every item in a list, but individual users are only allowed to edit the specific tickets assigned to them.

How to Restrict Editing at the Item Level in Microsoft Lists

Product: Microsoft Lists
Device & OS: not provided
Scenario: Managing team workloads and ticket assignments where specific item-level edit access needs to be dynamically granted based on the assigned specialist.
Observed behavior: Microsoft Lists does not offer a simple, built-in setting for assignment-based editing models, requiring external workarounds to achieve this level of permission control.

Before you start

Ensure you have Site Owner permissions for the underlying SharePoint site and access to Microsoft Power Automate, as this solution requires creating a custom flow to modify permission inheritance.

Use Power Automate to Assign Item-Level Permissions

Create a custom Power Automate flow to break default permission inheritance on SharePoint list items and grant edit access dynamically based on the assigned specialist.

Because Microsoft Lists is built on SharePoint, it inherits standard site permissions by default. There is no simple toggle to restrict edits based on an 'Assigned To' column.

To achieve an assignment-based editing model, you must use a Power Automate flow. This flow will trigger whenever a ticket is created or updated, remove the default inherited edit permissions, and specifically grant edit rights only to the person assigned to the ticket.

Create a new Power Automate flow

Log in to Power Automate and create an 'Automated cloud flow'. Set the trigger to 'When an item is created or modified' and link it to your specific Microsoft List and Site Address.

Break permission inheritance

Add a new action and search for 'Stop sharing an item or a file' (SharePoint). Select your list and use the dynamic content 'ID' from the trigger to target the specific list item. This removes standard edit access for general members.

Grant access to the assigned specialist

Add another action called 'Grant access to an item or a folder' (SharePoint). Point it to the same List and Item ID. In the 'Recipients' field, insert the dynamic content for the 'Assigned To Email' and set the Roles parameter to 'Can edit'.

Test your custom flow

Save your flow and create a test item in your Microsoft List. Verify that the assigned specialist can edit the ticket while other team members only retain 'View' access.

Use Power Automate to Assign Item-Level Permissions

Community Support for Power Automate: Custom flows for permissions can become complex, especially when handling re-assignments. If you need advanced design or security guidance, it is highly recommended to share your specific requirements in the official Power Automate Community forums.

Frequently Asked Questions

Can I restrict users to only see the items they created in Microsoft Lists?

Yes. If you simply want users to only read and edit their own entries, you do not need Power Automate. Go to List Settings > Advanced Settings, and under 'Item-level Permissions', select 'Read items that were created by the user' and 'Create items and edit items that were created by the user'.

Why does breaking permission inheritance cause performance issues?

SharePoint lists (which power Microsoft Lists) are optimized for inherited permissions. When you break inheritance on thousands of individual items to create unique permissions, it forces the system to calculate access rights row-by-row. This can lead to slower list loading times and eventually hit the SharePoint threshold limits.

Is it possible to restrict editing to a specific column rather than the whole item?

Microsoft Lists does not natively support column-level permissions. To restrict editing of a specific field (like a 'Status' column), you typically need to customize the list form using Power Apps to conditionally disable the field based on the logged-in user's role.
