Common mistakes
- Missing or incomplete MFA.
- Too many administrator accounts.
- Poorly controlled SharePoint and OneDrive external sharing.
- Incomplete SPF, DKIM or DMARC.
- Licences misallocated or protections not activated.
- No suitable backup strategy.
- Third-party apps and shadow IT not monitored.
Why audit regularly
Settings evolve with usage, teams and licences. Regular audits turn Microsoft 365 into a controlled platform rather than an accumulation of options.
Microsoft 365 has become a cornerstone of the digital environment for many organizations. Messaging, collaboration, document sharing, security, mobility, identity management… the platform now centralizes a large part of the company’s critical operations.
However, Microsoft 365 is constantly evolving.
Settings change, usage expands, licenses evolve, teams transform, and new features are regularly introduced.
Without clear governance, the environment can quickly become difficult to control.
This is why regularly auditing Microsoft 365 is no longer optional: it is a necessity.
A Platform That Continuously Evolves
Unlike traditional infrastructures, Microsoft 365 is a dynamic environment.
Every month, Microsoft introduces:
- new features;
- security updates;
- configuration changes;
- new compliance settings;
- license-related modifications.
At the same time, the organization itself evolves:
- new employees;
- staff departures;
- new usage patterns;
- the multiplication of Teams workspaces;
- more frequent external sharing;
- new connected devices.
Gradually, gaps appear between the initial configuration and operational reality.
Auditing helps organizations regain control.
Identifying Invisible Risks
In many Microsoft 365 environments, certain risks often go unnoticed:
- inactive accounts that are still enabled;
- overly broad access rights;
- uncontrolled external sharing;
- disabled MFA;
- unused licenses;
- poorly protected sensitive data;
- obsolete Teams or groups.
These situations may not always be visible on a daily basis, but they significantly increase the risks of:
- data breaches;
- configuration errors;
- non-compliance;
- unnecessary costs;
- security vulnerabilities.
Regular audits make it possible to identify these drifts before they become critical.
Regaining Control Over Costs
Microsoft 365 is also a financial matter.
Over time, many organizations accumulate:
- unused licenses;
- redundant options;
- activated but underused services;
- subscriptions that no longer match actual needs.
An audit helps analyze the real usage of licenses and services in order to:
- optimize costs;
- rationalize subscriptions;
- improve budget visibility;
- avoid unnecessary spending.
The objective is not only to reduce costs, but also to align investments with actual business needs.
Security and Compliance: An Ongoing Challenge
Microsoft 365 has become a preferred target for cyberattacks.
Phishing, account compromise, unsecured access, excessive sharing, or poor identity management can have major consequences for business operations.
A regular audit helps verify:
- security policies;
- administrator access rights;
- MFA mechanisms;
- sharing rules;
- retention policies;
- the protection of sensitive data;
- compliance-related configurations.
With regulations such as NIS2 or GDPR, organizations must demonstrate stronger control over their digital environments.
Auditing therefore becomes a governance and risk-reduction tool.
Transforming Microsoft 365 into a Controlled Platform
Without proper governance, Microsoft 365 can quickly become an accumulation of options, configurations, and inconsistent usage patterns.
The purpose of an audit is not purely technical.
It is about transforming Microsoft 365 into a platform that is:
- consistent;
- secure;
- well-managed;
- aligned with business needs;
- adapted to the organization’s strategy.
This approach also helps improve:
- user experience;
- collaboration;
- document governance;
- service continuity;
- operational resilience.
What Selection ICT Brings in Practice
At Selection ICT, we support organizations in auditing and optimizing their Microsoft 365 environments.
Our approach aims to:
- improve visibility into usage;
- identify risks and inconsistencies;
- strengthen security;
- optimize licenses and costs;
- structure Microsoft 365 governance.
Because a high-performing cloud environment does not rely solely on technology, but also on clear and sustainable governance.
Conclusion
Microsoft 365 is a powerful platform, but its complexity increases over time and with evolving usage.
Settings evolve alongside teams, licenses, and business requirements.
Regular audits help maintain a clear vision of the environment, anticipate risks, and sustain a level of security, compliance, and performance aligned with organizational challenges.
A well-managed platform will always be more effective than an uncontrolled accumulation of features and options.
