Hi @Bhupal Koushik ,
Hope you are doing well.
As per the details provided, you are facing "Too Many Requests (throttle) issue" with MS Graph.
When experiencing throttling, which happens when the number of requests exceed the rate at which the destination can handle over a specific amount of time.
When it comes to MS Graph API throttling, we suggest:
- Reduce the number of operations per request.
- Reduce the frequency of calls.
- Avoid immediate retries, because all requests accrue against your usage limits.
There are some best practices to avoid the throttling while using the Graph API requests.
- Wait the number of seconds specified in the retry-after header.
- Retry the request.
- If the request fails again with a 429-error code, you are still being throttled. Continue to use the recommended retry-after delay and retry the request until it succeeds.
If no retry-after header is provided by the response, we recommend implementing an exponential backoff retry policy. You can also implement more advanced patterns when building large-scale applications.

Also, we have some service specific limits in regards with different O365 workloads. Please refer this Microsoft document for this- Microsoft Graph throttling guidance - Microsoft Graph | Microsoft Learn
JSON batching allows you to optimize your application by combining multiple requests into a single JSON object. Please refer this documentation for more information on batching- Microsoft Graph throttling guidance - Microsoft Graph | Microsoft Learn
Hope this helps.
