Signs Your Microsoft 365 Environment Needs an Audit

1. Nobody can name your Global Admins

If leadership can't quickly answer 'who are our Microsoft 365 Global Admins?', the tenant has drifted. A healthy tenant has two or three named humans with Global Admin, each with phishing-resistant MFA, and documented.

2. MFA coverage is 'mostly'

MFA needs to be all-or-nothing. Any gap especially service accounts, contractors, or an executive with a bypass is where attackers land.

3. Licence spend is climbing but nobody knows why

Departing staff still licensed, users on Business Premium who need only Standard, dormant SKUs from old projects Microsoft 365 licence bills grow quietly. An audit routinely reclaims 10 20% of monthly spend.

4. External sharing is unknown

If nobody can produce a report of which SharePoint sites are shared externally and with whom, that's a sign sharing has been left at defaults and drifted.

5. Sign-in issues, MFA prompts, and 'weird' emails are increasing

Rising strange behaviour often precedes a discovered breach forwarding rules quietly added, sign-ins from unfamiliar locations, or spikes in blocked sign-ins. Audit logs can confirm or rule out.

6. Cyber insurance renewal asked questions you couldn't answer

Insurance questionnaires now ask about MFA coverage, admin roles, backup, and endpoint management. If your last renewal required guessing on any of these, an audit gets you evidence you can attest to.

7. No Microsoft 365 backup, or you're not sure

If you can't name the backup product, retention length, and when the last restore was tested, backup is not in place in any meaningful sense.

8. Teams and SharePoint have sprawled

Hundreds of Teams, orphaned channels, stale sites. Users can't find current documents. Search returns three versions of the same file. Governance never happened, and it's affecting productivity.

9. You inherited the tenant and have no documentation

New IT lead, new MSP, or acquired the business audits build the baseline documentation nobody left behind. This is the most common audit trigger we see.

10. It's been more than a year since anyone reviewed the tenant

Microsoft 365 changes constantly new features arrive with new defaults, and old defaults quietly loosen. An annual tenant review is basic hygiene.

What a Microsoft 365 audit actually delivers

• Current-state security posture and Secure Score
• Admin role and MFA coverage report
• Licence utilization report and right-sizing recommendations
• External sharing, guest access, and mailbox forwarding review
• Prioritized remediation plan with effort estimates
• Documented baseline so drift is visible next time

Common mistakes

• Waiting for a breach or a failed insurance renewal to trigger the audit
• Treating the audit as a one-time event instead of an annual cadence
• Auditing without a clear remediation owner nothing changes after the report is delivered

When to call an IT provider

If any three of the signs above apply, an audit is overdue. Most SMB Microsoft 365 audits take one to two days of work and produce a report and plan you can execute over the following weeks.
