Microsoft 365 Copilot — Safe Readiness

Microsoft 365 Copilot is only as safe as your SharePoint, OneDrive, and Teams permission hygiene. The #1 incident pattern is "Copilot surfaced HR/board/legal content because the underlying site was over-permissioned." This skill is the end-to-end readiness playbook — identify oversharing, contain via SAM and labels, then enable Copilot in waves.

When to use

Preparing to deploy Microsoft 365 Copilot. Use for the pre-launch security workstream: oversharing detection, containment controls, label/DLP coverage, audit, and phased rollout.

Do not use this skill for the broader oversharing program (m365-oversharing), Purview DSPM for AI in isolation (purview-dspm-ai), or agent-specific security (microsoft-agent-365).
