Define the tenant and the review boundary
Record the tenant, business domains, identity source, subscriptions, user groups, administrators and important services in scope. Include external IT providers and the people who can recover the organization if the usual administrator is unavailable. An application or mailbox outside the chosen tenant is not automatically covered by the review.
Check the available administrator roles and licensing before promising a particular feature, report or automated policy. Use explicit statuses such as verified, needs change, unavailable under the current plan, not applicable or not yet tested. Missing access or retention is an evidence limit, not a passing check. Agree the review and any later implementation as separate authorized activities.
Protect administrative control and recovery first
Review who holds privileged roles and whether ordinary daily work uses unnecessary administrative access. Identify departed staff or supplier accounts, the business owner of each continuing role and how role changes are approved. A list of administrators is a starting inventory; verify the intended ownership and current use rather than removing unfamiliar accounts without checking dependencies.
Prepare and test protected emergency access using Microsoft's current guidance, with independent recovery arrangements, strong authentication and appropriate monitoring. A recovery account should not become an unmanaged password-only shortcut. Plan a safe test and a working administrative route before changing policies that could lock out the entire response team.
Verify authentication policy and coverage
Distinguish enrollment of an authentication method from a policy that requires it on the relevant path. Microsoft Entra security defaults and Conditional Access have different scope, capabilities and licensing considerations. Determine what the tenant actually uses and what its intended coverage is; do not combine copied settings from unrelated configurations as a generic baseline.
Review material accounts, application paths, legacy dependencies and documented exceptions with the responsible owner. Test a representative authorized sign-in without intentionally breaking the only administrator. Record the expected challenge or restriction, observed behavior and any remaining exception. A policy appearing enabled does not establish enforcement for every user, app or session.
| Review area | Evidence to request | Acceptance question |
|---|---|---|
| Administration | Privileged identities, business ownership and protected recovery test. | Can the right people administer and recover without unnecessary privilege? |
| Authentication | Configured policy, covered identities and controlled sign-in result. | Is the intended requirement enforced on the material paths? |
| Relevant forwarding, rules, delegation, domain settings and test messages. | Are the intended routes and senders accounted for? | |
| Sharing and apps | Material external access, app permissions and responsible owners. | Is access justified, scoped and reviewable? |
| Devices and evidence | Available management and reporting controls and relevant records. | What is actually enforced and what remains outside scope? |
| Change closure | Original state, approved delta and repeatable checks. | Did the change improve the intended control without breaking the business route? |
Review mail, shared data and application access
Inspect relevant forwarding, inbox rules, mailbox delegation and mail-flow arrangements against the business need. Review the domain-authentication routes for staff and material third-party senders separately. A Microsoft 365 staff-mail test does not validate every invoice or website platform using the same visible domain.
For shared files and connected applications, identify material external recipients, broad links, app permissions and ownership of the integration. Confirm which access is still justified before making a bulk change. A supplier may need a narrower role or scope instead of permanent broad access, while a business-critical connector needs a tested replacement before its permissions are removed.
Check available evidence and implement changes safely
Determine which sign-in, audit, mail and device observations are available to the authorized reviewer and for what period. Correlate a specific test or concern with that evidence. Do not interpret a missing record as proof that an action did not occur. If suspicious access is already present, move to the incident workflow rather than treat it only as a future improvement ticket.
Prioritize changes by business exposure, dependencies and recovery readiness. Preserve the original settings, define a scoped change and test a controlled group where appropriate before broader enforcement. Record who approves the action, what indicates success and what triggers reversal. A checklist should produce an accountable action register, not a collection of unexplained screenshots.
Close the review with verified outcomes and limits
Repeat the relevant access, mail and sharing checks after approved changes. Report what was verified, what could not be examined, which improvements need a different plan or specialist and who owns follow-up. A technical configuration review is not a blanket compliance certification, penetration test or managed monitoring service.
