Detailed Microsoft 365 Email & Group Access Audit
CEO-facing access matrix based on the PowerShell checks performed during the Tenbex Microsoft 365 audit. It identifies who can open Shared Mailboxes, who is a member of Microsoft 365 Groups, who is subscribed to group conversations/notifications, forwarding paths, external identities, legacy identities, ownerless groups and governance risks.
Executive Summary
User Mailboxes / Functional Addresses
| Mailbox | Observed access / forwarding | Risk | Assessment |
|---|---|---|---|
| Enquiry [email protected] | Forwards to [email protected]; DeliverToMailboxAndForward=True. Enquiry Team observed member: Faiz — [email protected]. | MEDIUM | Functional address is a UserMailbox rather than Shared Mailbox; direct-login/lifecycle model should be reviewed. |
| Fleet Manager [email protected] | No explicit FullAccess delegates or forwarding detected. | LOW | Low relevance to shared-access risk. |
| Admin Primavera [email protected] | No explicit FullAccess delegates or forwarding detected. | LOW | Review business purpose only. |
| Backup File [email protected] | No explicit FullAccess delegates or forwarding detected. | LOW | Review business purpose only. |
| TESB UTP [email protected] | No explicit FullAccess delegates; no mailbox forwarding; no inbox forwarding/redirect rule detected. | MEDIUM | Functional UserMailbox. Document why a direct-login user identity is required, or consider Shared Mailbox if it is truly a role address. |
Audit Limitation, Fairness & Governance Context
This audit is a technical access review based on Microsoft 365 / Exchange Online evidence. It is designed to identify where management validation is required, not to make assumptions about an employee's job scope, seniority, authority or business need.
Important limitation of this audit
The audit did not have a complete and authoritative source for every employee's official job title, current department, project appointment, delegated authority, management responsibility or business justification. Therefore, the presence of a user in multiple Microsoft 365 Groups, Shared Mailboxes or sensitive functional groups does not automatically mean the access is incorrect or unauthorized.
A user may legitimately require broader access because of management duties, cross-functional responsibilities, project assignments, temporary operational requirements, committee appointments or specific instructions from authorized management.
Management validation is required before any access is removed
Findings such as access to TOP MANAGEMENT, Finance, HR, IT, QA, HSE, Procurement, Sales or other cross-functional groups should be treated as management review points, not as automatic violations. The final decision on whether an individual should retain or lose access should be made by the relevant Business Owner, Department Head, CEO or Top Management based on the person's actual responsibility and authority.
Principle of Authority / Punca Kuasa
For good governance, every material access decision should have a clear and traceable source of authority (punca kuasa). This protects both the company and the administrator who implements it.
- Management or Board/Executive meeting decision.
- CEO / Top Management instruction or formally recorded veto/approval.
- Department circular, SOP or policy.
- Approved job description or responsibility matrix.
- Project appointment letter / project organization chart.
- Business Owner or Department Head approval.
- Contractual or client requirement.
- Time-bound emergency or operational authorization, followed by review.
Best-practice decision model
Business Management authorizes access; IT implements and records it.
IT administrators should not become the permanent sole decision-maker for who is entitled to confidential departmental or management information. Their role is to implement approved access, enforce technical controls and maintain an audit trail.
Business Owners and management are responsible for deciding whether access is justified and accepting the corresponding business risk.
Minimum Access Authorization Record
Tenbex should maintain a simple access register so every important permission can be explained during management review, client audit, staff transfer or employee offboarding.
| Required Field | Purpose | Example |
|---|---|---|
| User / Identity | Who is receiving access. | Siti Nur Khadijah — [email protected] |
| Resource | Mailbox, group, Team, SharePoint site or application. | [email protected] |
| Business Reason | Why the access is necessary. | Management coordination / approved project responsibility |
| Approver / Punca Kuasa | Who authorized the access. | CEO / Top Management / Department Head |
| Approval Reference | Evidence that can be traced later. | Management Meeting MM-2026-08 / departmental circular / approved email |
| Effective Date | When access became valid. | 01 Aug 2026 |
| Review / Expiry Date | When access must be recertified or removed. | 31 Dec 2026 / project closeout |
Fairness statement
This report does not assign blame to any individual user or previous administrator. Its purpose is to help Tenbex ensure that every access to company information assets has a legitimate business reason, documented authority, accountable owner, periodic review and appropriate security control.
Where access cannot currently be linked to a documented source of authority, the correct response is management validation and governance improvement — not an immediate assumption of misconduct.
Recommended wording for management decisions
Use: “Membership requires management validation against current role, responsibility and authority.”
Avoid: “This user should not be in this group.”
This distinction keeps the audit factual, fair and defensible while still highlighting security and governance issues that require executive attention.
Individual User Access Concentration & Role Alignment
This section reverses the audit view: instead of asking “who is inside each group?”, it shows how many different company mail/group resources each individual can access. This is important for segregation of duties, need-to-know, privacy and management accountability.

Specific example requiring management validation
Siti Nur Khadijah — [email protected] was observed as a member of 19 Microsoft 365 Groups. These included HSE, IT, QA, TOP MANAGEMENT, Proposal, Project Management 1, Center of Excellence, EFEMS, HRAQ, Porcument, HR1, Sales157, Finance982, PREFCHEM, PRefChem59, PTTEP802, BackupData, SKA and EPCC.
The audit cannot determine from Exchange data alone whether each membership is appropriate to her HR/job role. The CEO/business owners should specifically validate sensitive memberships such as TOP MANAGEMENT, Finance-related, HR-related, IT, QA and other cross-functional groups against current responsibility and authority.

The current retained audit record preserves the 76-object total and these external addresses, but not the complete 76-name roster. Re-exporting this DG to CSV is recommended for a complete CEO annex.
Identity Governance Findings
Legacy Shahiffudin identity
Legacy non-mailbox User: [email protected]
Object ID: d116c616-b695-4806-92e7-55f200e7848a
AccountDisabled observed: False
Separate current mailbox: [email protected]
Object ID: ef69cba6-ff11-4de8-b83d-0a1479e1dc13
The legacy object remained a member of PTTEP, red and SEAH-LCOT; in red it was owner + member + subscriber.
Other enabled non-mailbox Users
- Mohamad Afif Mohd Shahimee — [email protected]
- Anita Mokhtar — [email protected]
- Mohd Aiman bin Md Tasyrif — [email protected]
- Mohamad Johari bin Dasri — [email protected]
For all four, Exchange showed RecipientTypeDetails=User, no Primary SMTP and AccountDisabled=False. This is not by itself proof that interactive Entra sign-in is enabled.

CEO Governance Conclusions
Current practice
- Shared Mailboxes for HR/Admin/Procurement/Sales are a good technical pattern.
- Group lifecycle governance is inconsistent.
- External access and personal Gmail exist in collaboration groups.
- Parallel functional groups make authoritative access unclear.
- Legacy identities were not consistently retired when newer mailbox identities existed.
Required governance
- One canonical identity per employee.
- Shared Mailbox for multi-user general inboxes; no shared passwords.
- At least two accountable owners for retained M365 Groups/Teams where practical.
- Business approval + expiry/review date for external guests.
- Quarterly access certification for general/sensitive resources.
- Project closeout SOP covering email, Teams, SharePoint and guest access.
- Central Email & Group Register.
