Intune On-Demand Proactive Remediation API Reliability for Large-Scale Usage

Hi Team,

We are testing the Intune On-Demand Proactive Remediation API:

POST /deviceManagement/managedDevices/{managedDeviceId}/initiateOnDemandProactiveRemediation

In our environment, the remediation package works correctly, and the API generally triggers the remediation as expected. However, during repeated testing, we noticed that a small percentage of requests do not seem to reach the endpoint.

For example:

• 20 remediation requests sent
• 18-19 execute successfully
• 1-2 never trigger on the target device
• Devices are online and managed by Intune
• Added a 30-second delay between requests, but the behavior still occurs intermittently

Before adopting this in production for a large client base, we'd like to understand:

• Has anyone observed similar behavior?
• Is this API reliable for triggering remediation across multiple devices in parallel?
• Are there any known limitations, queueing mechanisms, throttling considerations, or best practices?
• Is there a recommended way to verify that a remediation request was actually delivered to the device?
• Since this API is still in the beta/preview stage, is there any information on its roadmap or GA timeline?

Note: For additional context, detailed test results, observations, and environment information, a PDF containing the complete analysis has been attached.

Any guidance or real-world experience would be greatly appreciated.

Thank you.
