Microsoft keeps Copilot audit logs for 180 days. Your auditors expect 7 years.
Capture and store Copilot interaction audit data beyond Microsoft's retention limits.
Overview
Every Copilot interaction generates an audit event (RecordType 261, CopilotInteraction) in Microsoft's Unified Audit Log. These records capture who used Copilot, when, in which app, and what files were referenced. On E3 licenses, Microsoft retains this data for just 180 days. Even E5 provides only one year. HIPAA requires 6 years. SOX mandates 7 years. The average time to detect a sophisticated data breach is 290 days - beyond E3's entire retention window.
Compass Copilot Audit Log Retention runs a Python Azure Function that subscribes to the Office 365 Management Activity API and captures CopilotInteraction events in near-real-time. Structured metadata is stored in Azure SQL for fast querying, while raw event payloads are stored in Azure Table Storage at a fraction of the cost. A React compliance dashboard provides search, filtering, and export capabilities for audit readiness.
