Summary
This module gives you a repeatable way to move Microsoft 365 Copilot from a small pilot to a full tenant rollout without exposing data nobody intended to share. You now know how to read a tenant's readiness signals, close oversharing gaps before they surface, and pace a rollout so each wave lands on a foundation that's actually tested.
What you learned
- The Microsoft 365 Copilot Readiness Report shows which users hold a license, sit on a Copilot-eligible update channel, and show activity in Teams, Outlook, and Office apps, so you can target the next licensing wave instead of guessing at it.
- Data readiness confirms what Copilot can already reach through a user's existing permissions, and the oversharing remediation sequence—assess, grant, protect, and control access—closes exposure that a small pilot never surfaces on its own.
- A phased rollout that moves through pilot, validate, and expand confirms that data-readiness remediation actually holds before a larger population reaches the same content, turning rollout pacing into a risk-management control instead of a project calendar.
