Extend Microsoft 365 Audit Log Retention Limits


Extending Your Audit Log Retention Limits in Microsoft 365

Many organizations using Microsoft 365 E3 licenses face a key challenge: extending audit log retention beyond the default 180 days. Maintaining long-term audit logs is essential for GxP compliance and cybersecurity. Our Audit Vault for M365 solution enables you to retain Microsoft audit logs for as long as you need them, ensuring your organization meets it's compliance and security requirements.


Microsoft's Current Audit Log Retention Limits

Microsoft 365 E3 licenses only retain audit logs for 180 days, creating serious challenges for organizations that need long-term data retention for compliance and security. After this period, critical audit data is permanently deleted, increasing the risk of regulatory violations, security gaps, and loss of legal audit trails. Extending retention through Microsoft requires costly E5 upgrades or additional licensing, driving up expenses for organizations that need to maintain a historical chain of custody.

Microsoft 365 Audit Log Retention Options
License Retention Details
Microsoft E1 180 days Audit (Standard)
Microsoft E3 180 days Audit (Standard)
Microsoft Office 365 180 days Audit (Standard)
Microsoft Office 365 E5 1 year Audit (Premium)
Microsoft 365 E5 1 year Audit (Premium)
Microsoft E5 (Extended Retention) 10 years Extended Retention
Audit Vault for M365 Unlimited Standard


It's important to note that the retention period is determined by the Microsoft license assigned to the user who performed the audited activity, not the administrator or auditor reviewing the logs.
