Returns the tenant's employee-reported (suspicious) emails as overview records, with summary counts. Each record includes a readable AI classification (AIAttribution), attachment metadata, and the received/reported timestamps normalised to ISO-8601 UTC. Everything is returned in one response by default; pass page and/or pageSize for a newest-first slice instead (the response then also carries TotalCount, Page, PageSize and HasMore). If an unpaged result would exceed the response size limit, the newest 1000 records are returned with Truncated=true and TotalCount so you can switch to paging for the rest.
