What Most Small Businesses Don’t Know About Their M365 Setup
When a business sets up Microsoft 365, the focus is usually on getting email working and making sure everyone can access Teams and SharePoint. The security settings, compliance configurations, and admin controls get left at whatever the defaults happen to be.
That’s understandable — Microsoft 365 is complex, and most small businesses don’t have a dedicated IT security person. But those default settings aren’t designed with your specific business in mind. They’re designed for the average organisation, which means they may be too permissive, misconfigured, or simply not appropriate for your situation.
A Microsoft 365 configuration review is the process of systematically examining every relevant setting in your tenant to identify gaps, risks, and opportunities for improvement.
What Gets Reviewed
A thorough M365 configuration review covers every area of your tenant that affects security, compliance, and efficiency. Here’s what that typically includes:
Identity and Access
This covers how users authenticate and what they can access. Key areas include Multi-Factor Authentication (MFA) status for all users, Conditional Access policies, admin role assignments, and legacy authentication settings. Identity is the most common entry point for attackers, so this section almost always surfaces findings.
Email Security
Exchange Online has a range of anti-phishing, anti-spam, and anti-malware settings that need to be properly configured. This includes Safe Links, Safe Attachments, DKIM, DMARC, and SPF records — the technical controls that prevent email spoofing and protect against malicious links.
SharePoint and OneDrive Sharing
File sharing settings are one of the most overlooked areas in M365. Default settings often allow files to be shared with anyone who has a link — no sign-in required. A review examines external sharing policies, default link types, and whether sensitive data is appropriately protected.
Defender for Business
For businesses on Microsoft 365 Business Premium, Defender for Business provides endpoint protection against malware, ransomware, and phishing. A review checks whether Defender is active, devices are onboarded, and protection policies are correctly configured.
Licensing and User Accounts
License assignments are reviewed to identify unused, over-assigned, or incorrectly assigned licenses. Former employee accounts, shared mailboxes, and service accounts are also examined — these are common sources of security risk and unnecessary cost.
What You Get at the End
A Microsoft 365 configuration review isn’t just a list of problems. The deliverable is a written report that includes:
- An executive summary written in plain language for non-technical readers
- A detailed findings list with risk ratings (High, Medium, Low)
- An explanation of each issue and its potential business impact
- Step-by-step remediation instructions your team can act on
- A prioritized action plan so you know what to fix first
The goal is to give you a clear, actionable picture of where your Microsoft 365 environment stands — and exactly what to do about it.
How Long Does It Take?
The review itself takes 1–3 business days and is done entirely remotely using read-only access to your Microsoft 365 admin center. There’s no interruption to your day-to-day operations. The written report is typically delivered within 5 business days of completing the audit.
Who Is It For?
A Microsoft 365 configuration review is most valuable for:
- Small to mid-size businesses that set up M365 themselves or with minimal IT guidance
- Businesses that have never had their M365 environment independently reviewed
- Organisations preparing for a compliance audit or cyber insurance renewal
- IT managers who want a second opinion on their current configuration
- Businesses that have recently experienced a security incident and want to understand their exposure
Is It Worth It?
The average cost of a data breach for a small business runs into tens of thousands of dollars — and that’s before you factor in reputational damage, regulatory fines, and lost business. A Microsoft 365 configuration review is a fraction of that cost and gives you the information you need to significantly reduce your exposure.
More practically — most reviews pay for themselves. The licensing optimisation findings alone typically identify enough unused or incorrectly assigned licenses to cover the cost of the review within a few months.
