Microsoft Copilot Readiness
How to review SharePoint permissions before Microsoft Copilot
Microsoft Copilot respects the permissions users already have. That makes permission quality, external sharing, site ownership, and information hygiene essential readiness issues—not optional cleanup after deployment.
A permission review should answer a simple question: can every user access only the information appropriate for their role, and can the organization explain who approved that access? The following process creates a defensible baseline before pilot or production rollout.
1. Establish the review scope
Identify the SharePoint sites, Teams-connected sites, OneDrive locations, groups, guests, and business units included in the Copilot pilot or rollout. Prioritize executive, legal, human resources, finance, security, contracting, and other sensitive repositories.
2. Confirm accountable site ownership
Every in-scope site should have a current business owner who understands its purpose, users, data sensitivity, and acceptable sharing model. Sites without an accountable owner should be restricted, reassigned, or excluded until ownership is resolved.
3. Identify broad and inherited access
Review organization-wide groups, “everyone” access, large security groups, nested groups, inherited permissions, and default sharing settings. Broad access may have been convenient for collaboration but may no longer match business need.
4. Find unique permissions and broken inheritance
Folders, files, libraries, lists, and subsites with unique permissions are difficult to govern consistently. Record why inheritance was broken, who approved the exception, and whether the exception remains necessary.
5. Review guests and external sharing
Identify guest accounts, anonymous links, “specific people” links, expired collaborations, external domains, and sites that allow broader sharing than intended. Remove stale access and establish an owner-approved review cycle.
6. Validate sensitive-content locations
Confirm where sensitive, regulated, privileged, personnel, financial, or contract information is stored. Review whether access, labeling, retention, and sharing controls match the actual content.
7. Clean up stale users and groups
Remove former employees, obsolete groups, duplicate groups, inactive guests, and temporary access that was never revoked. Document exceptions that must remain.
8. Test with representative users
Use pilot accounts from different roles to validate what users can discover, search, summarize, and retrieve. Testing should include both expected access and information that users should not be able to reach.
9. Create remediation and monitoring controls
Assign owners, priorities, due dates, and validation evidence for each finding. Define ongoing ownership reviews, guest reviews, sharing controls, access recertification, and escalation paths after rollout.
Permission review evidence leadership should receive
- List of in-scope sites and accountable owners
- Broad-access and unique-permission findings
- Guest and external-sharing inventory
- Sensitive-content risk observations
- Stale-user and group cleanup actions
- Prioritized remediation plan
- Pilot validation results
- Ongoing review and monitoring responsibilities
A broader readiness review should also address acceptable use, information quality, training, privacy, accountability, and pilot success measures. See the Microsoft Copilot governance readiness assessment.
Prepare permissions before Copilot expands discovery.
PPS can assess ownership, oversharing, external access, documentation, acceptable use, training, and pilot readiness before rollout.
