Module 19: Admin, Security, Privacy, and Governance
Lesson 19.3: Data Permissions, SharePoint, OneDrive, and Oversharing
Lesson Promise
Prepare data so Copilot improves productivity without amplifying oversharing.
Real-World Scenario
IT discovers old SharePoint sites, broad sharing links, ownerless files, and sensitive documents before a Copilot rollout.
Core Concept
Copilot can make existing information easier to find, which means overshared content can become a business risk.
Data readiness includes reviewing high-risk sites, sensitive files, sharing links, ownerless content, inactive sites, and permission groups.
Governance is continuous. New sites, files, and agents need secure defaults and review routines.
Step-By-Step Workflow
- Identify high-risk sites, sensitive content, and broad sharing links.
- Review ownerless, inactive, stale, duplicate, and externally shared content.
- Apply least-privilege permissions and secure sharing defaults.
- Use labels, restricted access, or DLP where appropriate.
- Create owner accountability and review cadence.
- Train users to manage files before asking Copilot to reason over them.
Prompt Lab
Bad Prompt
Clean up SharePoint for Copilot.
Better Prompt
Identify overshared, sensitive, ownerless, and stale content before expanding Copilot access.
Expert Prompt
Create a Copilot data-readiness plan for SharePoint and OneDrive. Include high-risk sites, oversharing signals, external links, ownerless content, stale content, sensitive files, permission remediation, secure defaults, labels, review owners, and rollout gates.
Hands-On Exercise
Create an oversharing audit checklist for a sample department.
Deliverable
A SharePoint and OneDrive Copilot data-readiness checklist.
Governance Review Checklist
Common Mistakes
- Assuming Copilot can see everything in the tenant instead of respecting user access boundaries.
- Buying licenses before cleaning up high-risk sharing and ownerless content.
- Ignoring sensitivity labels, retention, audit, DLP, and Purview workflows.
- Treating agent approval as a one-time app decision instead of lifecycle governance.
- Training users on prompts without training them on sources, privacy, and review.
