Review external sharing in Microsoft 365.

What to inspect

Check anonymous links, guest users, site permissions, ownership, sensitivity and sharing defaults across Teams, SharePoint and OneDrive.

Govern sharing

Clear rules, reviews and sensitivity-based controls keep collaboration possible without losing oversight.

Why this matters for Microsoft 365 Security and AI

This topic becomes especially important when Microsoft 365 is no longer just used technically, but needs to be operated reliably across security, compliance, governance and AI readiness. Individual settings are not enough. Organizations need a clear assessment, owners and a sequence that balances risk, effort and value.

For small and mid-sized organizations, a pragmatic first step is usually more useful than a large program. A short check shows which measures create immediate value, which topics need preparation and where implementation should follow later.

Next step

The Microsoft Cloud Security Quick Check helps identify which Microsoft 365 security, governance or AI readiness topics should be addressed first.
