External Sharing in SharePoint and OneDrive is changing: What You Need to Know

In an ongoing effort to create a more secure environment by default, Microsoft is introducing an important security update that will affect how external users access content shared through SharePoint and OneDrive. Starting July 1, 2025, any links shared with external users before your organization enabled Microsoft Entra B2B integration will no longer work. This change applies to all organizations that have already enabled or will enable SharePoint and OneDrive integration with Microsoft Entra B2B (Most organizations I have looked into so far).

Copilot Pages: A New way of sharing and interacting with your data generated with Copilot

Back in November 2024, Microsoft Copilot users signed in with an Entra account started getting the new feature called Copilot Pages. Copilot Pages offers a dynamic, persistent canvas within Copilot chat, designed to enhance multi-player collaboration.

With Copilot Pages, you can share and improve the responses you get from Copilot. This feature is great start on evolving Copilot from an individual tool to a collaborative experience.

You can easily return to a page by clicking the link in chat or the Open Page icon at the top of the associated Copilot session. Additionally, all your pages are accessible in the Pages module on Microsoft365.com, where you can continue to collaborate with others. Created pages are stored in a user-owned SharePoint Embedded container, which is managed with the user account and deleted when the account is removed.

The feature was turned on by default, but there are ways for IT administrators to manage it. The full details are available on Microsoft Learn, but here is a brief description for your convenience:

Steps to Manage Copilot Pages:

  • Sign in to https://config.office.com with your admin credentials.
  • Navigate to Customization and select Policy Management.
  • Create or edit a policy configuration.
  • Choose the scope (All users or specific groups).

    • Not configured: Copilot chat experience is available.

Changes to policy configurations may take up to 90 minutes to reflect if there were existing policies, or up to 24 hours if there were no prior configurations.
