Low severityauthentication
Power BI Error:
AADSTS90024
What does this error mean?
Transient throttling error from Entra ID (Azure AD) — the request exceeded an internal token-service budget and should be retried.
Common causes
- 1Transient capacity/throttling on the Entra ID (Azure AD) STS token endpoint
- 2Application or service principal acquiring tokens in a tight loop instead of caching them (MSAL token cache not used)
- 3High burst of concurrent sign-ins or refresh-token redemptions from the same tenant or app within a short window
- 4Power BI / ADF / Fabric pipelines that re-authenticate per activity instead of reusing a valid access token
- 5Downstream Microsoft service retrying authentication aggressively after an unrelated upstream failure
How to fix it
- 1Retry the failed operation with exponential backoff (e.g. 5s, 15s, 60s) — AADSTS90024 is explicitly classified as transient by Microsoft.
- 2If the error repeats, inspect the calling app/service principal: ensure MSAL (or ADAL legacy) token caching is enabled and you are not requesting a new token per request — reuse the access token until it expires.
- 3For Power BI / Fabric scheduled refreshes or ADF pipelines: stagger refresh schedules and reduce parallel activities sharing the same service principal to lower the per-app request rate.
- 4Check Entra ID sign-in logs (Entra admin center → Monitoring → Sign-in logs) filtered on error code 90024 to identify which application or service principal is generating the volume.
- 5If throttling persists across retries, open a Microsoft support ticket with the correlation ID and timestamp from the failed request — sustained 90024s on a single tenant warrant an STS-side investigation.
