Power BI Error:
AADSTS51000, tenant feature disabled
What does this error mean?
Sign-in blocked because a required Azure AD / Entra ID feature or license is not enabled on the tenant.
Common causes
- 1The tenant lacks the Entra ID P1/P2 license required by a feature the app depends on (e.g. Conditional Access, risk-based policies)
- 2A preview or premium feature referenced by the application is not enabled in the Entra ID tenant
- 3Service principal or app registration requests a capability (e.g. token protection, CAE) that the tenant has not turned on
- 4User has no license assigned that includes the required feature, even though the tenant supports it
- 5Cross-tenant access or B2B collaboration setting relies on a feature the resource tenant has disabled
How to fix it
- 1Identify which feature is required: check the application's documentation or the sign-in log Additional Details in Entra ID → Sign-in logs for the failed request
- 2In the Microsoft Entra admin center, verify the tenant has the matching license SKU (Entra ID P1/P2, Microsoft 365 E5) and assign it to the affected user(s)
- 3If the feature is a preview / opt-in (e.g. Continuous Access Evaluation, token protection), enable it under Entra ID → Security or Conditional Access
- 4For B2B / multi-tenant apps: confirm the resource tenant has the feature enabled, not just the home tenant — AADSTS51000 is evaluated against the resource
- 5Re-test sign-in; if it still fails, raise a Microsoft support case with the correlation ID from the sign-in log — this error is tenant-config, not app-code
