- What it is
- Microsoft's reference for the audit records an enterprise tenant generates when a user interacts with Microsoft Copilot or another AI application, and for admin changes to Copilot settings. It lists the fields in each record and how long non-Microsoft AI interaction logs are kept.
- How much weight it carries
- Official Microsoft documentation, current when we checked. It describes what is logged, not who in an organization can read the logs, which depends on the tenant's roles and licenses. Retention periods can differ by license, so confirm them in the admin center.
