Can you restrict what Copilot can search across for in SharePoint?

Starting later this month (April 2024) , Microsoft will rollout an configuration setting called Restricted SharePoint Search (RSS) that will allow Global/Tenant and SharePoint Admins to disable organisation-wide search and instead select a set of curated/specific  SharePoint sites.

“YES YOU CAN”

This feature will work by allowing admins disable organisation-wide search, and instead to enable/restrict both specific sites impacting the scope of what Enterprise Search and Copilot can seek out and index when using search or Microsoft Copilot for Microsoft 365.

With this configuration in place, only these specific libraries along with the users’ OneDrive files and content, will be accessible in search and within the Copilot experiences.

This means that whether your organisation has Enterprise Search or Restricted SharePoint Search enabled, users in your organisation will still be able to interact with their OneDrive information in Copilot but there will be more control over excluding old/legacy or restricted SharePoint areas.

Why do we need to Restrict Search?

Is this not against the pricipals of Copilot and Microsoft Search?

Well.. Kinda. Restricted SharePoint Search has been provided to give organisations time to review and audit their data and SharePoint site permissions. Microsoft say that…

It is designed to help you maintain momentum with your Copilot deployment while you implement robust data security solutions from Microsoft Purview and manage content lifecycle with SharePoint Advanced Management. Combined, these two solutions offer a complete solution for data discovery, protection, and governance. “

Restricted SharePoint Search capability

Once Enterprise Search is disabled, Admins are the able be to tune which content will be indexed for search from an allowed list of up to 100 SharePoint sites. This will honor sites’ existing permissions.

Once configured, content from these areas will be searchable and accessible by Copilot as well as…

  • Content stored in the the curated list of SharePoint sites as specific by the admin.
  • Other frequently accessed SharePoint sites that the user accesses.
  • Content from users OneDrive, Teams chat, email, calendars.
  • Files directly shared with the user.

Copilot users in your organisation will see this message in their Copilot experiences.


Your organization’s admin has restricted Copilot from accessing certain SharePoint sites. This limits the content Copilot can search and reference when responding to your prompts

Does this mean Copilot can’t access files outside of the search scope?

No… Users can still directly reference a file in Copilot and access the file via manual search or navigation. This is because, restrictive search does not alter the permissions for user access, it just instead, is designed to help minimise the risk of overexposure of overshared content by reducing what they can discover in search and Copilot.

With Restricted Search configured, search results and Copilot search results will be limited but users will still able to navigate (as before) or directly link to a file to open or to “use Copilot” with.

Configuring Restricted Search

Restricted SharePoint Search is off by default.

Whilst this will be coming to the SharePoint admin pages soon… It will, at release be configurable via Power Shell only and will of course require admin privileges.

There is also an ‘allow’ limit of just 100 sites initially though I hear this will soon be expanded following early feedback from customer… Phew!
