Critical: All Microsoft Graph requests throttled at App level (50 RPM) since 29 April 2026

We are experiencing a critical production issue where all our Microsoft Graph requests are being throttled at the application level starting early morning 29th April 2026.

The throttling is happening under the category:

throttle.aad.ags.50RPM, which limits our application to 50 requests per minute.

This behavior is unexpected and appears to be a platform-side change, as our application has been functioning normally prior to this without hitting such limits.

Impact:

  • Affects all users (~120,000+)
  • Occurs across all tenants
  • Not limited to specific users or scenarios
  • Causing major disruption in production workflows
  • Core functionality dependent on Graph APIs is failing

Error Details:

{

"error": {

"code": "TooManyRequests",

"message": "Too many requests from Identifier:[Moderator note: personal info removed]  under category:throttle.aad.ags.50RPM. Please try again later.",

"innerError": {

  "date": "2026-04-29T03:40:25",

  "request-id": "[Moderator note: personal info removed] ",

  "client-request-id": "[Moderator note: personal info removed] "

}
```  }

}

    Hi Deepak Sharma

    Thank you for reaching out to the Microsoft Q&A forum and for taking the time to provide detailed information about your issue. I understand how critical this situation is, especially for production workloads.

    Based on the details you shared, I’ve reviewed the currently available documentation and resources, but I haven’t found any information that clearly explains this specific throttling behavior.

    Given that this appears to affect multiple tenants and users, and seems to be a sudden change, it will likely require a deeper investigation from the Microsoft Support team, who have access to backend service diagnostics.

    I recommend opening a support ticket through Service Hub so the support team can take a closer look and investigate further.

    Please note that access to the Services Hub depends on your organization’s support agreement and may require a paid support plan. You can review the requirements and sign-in conditions in the Services Hub sign-in FAQs before submitting a request. 

    Please understand that this is a public peer-to-peer community forum. While moderators and community members can share guidance and experiences, we do not have access to internal service diagnostics or the ability to investigate tenant-specific or backend service behavior.

    Thank you again for your patience and understanding. I will continue to monitor for any updates, and if new information becomes available, I will share it here.

    Note: Please follow the steps in our documentation to enable e-mail notifications if you want to receive the related email notification for this thread.
