Why this is relevant now
Microsoft is introducing new tools to manage permissions, transparency, and content hygiene in SharePoint—with a direct link to how Copilot and agents find and use data in both SharePoint and Microsoft Teams. Several features are generally available and aimed at administrators who want to reduce oversharing, secure searchability, and simplify operations in larger environments.
Permissions and visibility: reduce oversharing and unwanted Copilot results
Restricted Access Control (RAC) can now be used on all SharePoint sites, including those connected to Microsoft 365 Groups and Teams. With RAC, access is restricted through two-step control via Entra and M365 groups, helping quickly lock down overshared content. To prevent overly broad permissions from spilling into Copilot and the organization’s search, there is Restricted Content Discovery (RCD). When RCD is enabled on a site, its content is hidden from Copilot, search, and even custom agents until the appropriate level of access is ensured.

AI support in administration: faster policy comparisons and better oversight
AI-driven Site Matching compares reference sites with up to 10,000 target sites and flags deviations in areas such as external sharing, download blocking, and access policies. This enables a more consistent security posture without manual detail work. The SharePoint Admin Center also includes Copilot for admins, supporting natural-language queries, faster site search based on multiple attributes, summaries of recent changes, and contextual conversations. The goal is to shorten troubleshooting and make policy work more precise.

Agents and third-party apps: new insights at the site level
Agent Insights gives administrators visibility into how many SharePoint agents exist per site and enables actions such as enabling RAC or RCD where needed. For third-party access, Enterprise Application Insights shows which apps are accessing SharePoint and OneDrive sites, along with permission types and call counts. This facilitates review of external dependencies and reduces the risk of overexposed data.

Migrations and restore: support for tenant moves and stronger backup
Cross-tenant migration of SharePoint sites is now generally available, with redirects that preserve sharing links—relevant for mergers, acquisitions, and divestitures, including in Multi-Geo. On the resilience side, Microsoft 365 Backup strengthens data protection with dynamic rules in protection policies and email notifications to multiple admins for key events. Together with Microsoft 365 Archive, organizations can reduce storage costs while improving Copilot results by archiving inactive content.

What this means for SharePoint and Teams environments
In environments where Teams channels map to SharePoint sites, governance of permissions and visibility becomes critical for Copilot quality and compliance. RAC and RCD help quickly secure sensitive teams and channels, AI-driven Site Matching delivers consistent policies across many sites, and Copilot in the Admin Center shortens the time from insight to action. During major organizational changes, cross-tenant migration simplifies moving team site structures without breaking links.
