Permission drift is a real business risk

Microsoft 365 environments tend to expand quickly. New users are added, shared mailboxes accumulate, Teams channels grow, and permissions are granted temporarily but rarely reviewed later. Over time, that creates unnecessary access and elevated risk.

A quarterly review process helps businesses stay ahead of security drift while keeping collaboration productive.

What to review every quarter

• Admin roles and privileged accounts
• Shared mailbox access
• Teams, SharePoint, and OneDrive sharing settings
• Former employee account cleanup
• External user access and guest accounts
• Conditional access and MFA coverage

Why this matters

Over-permissioned accounts create exposure for phishing, business email compromise, data leakage, and compliance issues. Even simple cleanup steps can materially reduce attack surface.

Build the review into your operating rhythm

Quarterly reviews are most effective when ownership is assigned, findings are documented, and remediation deadlines are clear. This turns identity security into a routine process instead of an afterthought.
