For the past two months, our monthly Intune backup has been consistently failing only when it reaches the Administrative Templates section, where it immediately returns a 429 Too Many Requests error. This happens every time it tries to query the Administrative Template policies, and the error details match the ones shown in our PowerShell output (throttling via invoke-msgraphrequest, with repeated 429 responses across multiple GET calls under the /deviceManagement/groupPolicyConfigurations and /deviceManagement/groupPolicyDefinitionFiles endpoints). We tested adding static delays to the script and increased them gradually up to 5 seconds, but this has made no difference — the script still hits 429 responses immediately upon entering the Administrative Templates export. All other parts of the backup complete successfully, and we have not made any other modifications. Based on this behaviour, we’re trying to determine whether there has been a recent change to the throttling behaviour of these specific Intune endpoints, whether the script needs a different throttling/backoff strategy, or whether there is any recommended workaround for reliably backing up Administrative Templates without triggering continuous 429 errors?
