When a Graph-based tool syncs slowly or returns incomplete data, the cause is usually on the Graph side: throttling, pagination stalls, or transient 5xx errors that never surface in the UI.
This script captures the raw Graph request and response data, status codes, throttling headers, timings, and error bodies, so you can hand Microsoft Support something concrete instead of “it feels slow.”
Run it read-only against your tenant, reproduce the slow sync, and share the collected diagnostics with support to shorten the back and forth.
