Extend Microsoft 365 Audit Log Retention Limits


Extending Your Audit Log Retention Limits in Microsoft 365

Many organizations using Microsoft 365 E3 licenses struggle with a major challenge:

  • How to extend audit log retention beyond Microsoft's default 180 days limit.

Keeping long-term audit logs is crucial for GxP compliance and cybersecurity. Our Audit Vault for M365 solution allows you to retain your Microsoft audit logs for as long as you need them, ensuring your organization meets compliance and security requirements.


Microsoft's Current Audit Log Retention Limits

With a Microsoft 365 E3 license, audit logs are only retained for 180 days, which can be a serious issue for organizations that require long-term retention for compliance and security. Once this period ends, critical audit data is permanently deleted, increasing the risk of regulatory violations, security gaps, and the loss of legal audit trails. Extending retention through Microsoft often requires expensive E5 upgrades or additional licensing, making it costly for organizations to maintain a full historical record.


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.
