Hi G, Y,
Thanks for reaching out to Microsoft!
When throttling occurs, you'll receive an HTTP status code 429 (Too Many Requests). This response includes a Retry-After header indicating how long you should wait before retrying the request. Throttling can cause delays in processing your queries, as the service needs time to handle the backlog of requests.
Note: APIs under the /beta
version in Microsoft Graph are subject to change. Use of these APIs in production applications is not supported. To determine whether an API is available in v1.0, use the Version selector.
Hope this helps.
