Microsoft Teams: Meeting Participant Detail audit records will be available in all participating (non-organizer) tenants

Starting late August 2026, Microsoft Teams will share Meeting Participant Detail audit records with all participating tenants for their own users in cross-tenant meetings, enhancing audit visibility while maintaining data boundaries. No action is required, but admins may review audit processes accordingly. What and why Microsoft Teams audit logging is being enhanced to improve visibility for cross-tenant meetings. Meeting Participant Detail audit records will now be shared with all participating tenants, not just the organizer tenant. This change enables administrators to access participant-level audit information for meetings attended by users in their tenant, even when the meeting is hosted by another organization. This enhancement helps administrators better monitor and investigate Teams meeting activity involving users in their organization while maintaining tenant-level data boundaries. Rollout schedule General Availability (Worldwide): Beginning in late August 2026 and expected to complete by early September 2026 Impact on your organization Who is affected Microsoft 365 administrators who use Teams audit logs Organizations whose users participate in Teams meetings hosted by external tenants Platforms and services Microsoft Teams Microsoft Purview Audit What will happen After this rollout: Participating tenants will receive Meeting Participant Detail audit records for their own users who attended a Teams meeting organized by another tenant. The Meeting Participant Detail audit record includes organizer information, allowing administrators to identify whether a meeting was organized by their tenant or by an external organization. This change does not result in all Meeting Participant Detail audit records being shared with participating tenants. Participating tenants will receive only audit records associated with users from their own tenant. Participating tenants will not receive Meeting Participant Detail audit records for users belonging to other organizations that attended the same meeting. Action required and recommendations No action is required. Administrators may want to review any existing audit log collection, retention, or monitoring processes that consume Meeting Participant Detail audit records and assess whether the additional audit records affect those processes.
