Low severityauthentication
Power BI Error:
AADSTS50034
What does this error mean?
The signing-in user account does not exist in the Azure AD (Entra ID) tenant the application is configured for.
Common causes
- 1User mistyped their UPN (username) at the sign-in prompt
- 2User exists in a different tenant and was never invited as a B2B guest to this tenant
- 3Application is configured against the wrong tenant ID or uses /common while expecting a single-tenant audience
- 4Guest invitation was created but never redeemed, or the guest account was removed/soft-deleted
- 5On-premises AD account not yet synced to Entra ID via Azure AD Connect
How to fix it
- 1Verify the exact UPN the user is typing matches a user object in Entra ID (Azure AD) — search the user in the Entra admin center under Users > All users
- 2If the user belongs to an external organization, invite them as a B2B guest via Entra ID > External Identities > All users > New guest user, and have them complete the redemption email
- 3Check the application's authentication settings in Entra ID > App registrations: confirm the tenant ID in the authority URL matches the tenant where the user lives, and adjust 'Supported account types' if cross-tenant sign-in is needed
- 4For hybrid setups, confirm the user is in scope of Azure AD Connect sync and force a delta sync (Start-ADSyncSyncCycle -PolicyType Delta) if the account was recently created on-prem
- 5If the guest was previously deleted, restore from Entra ID > Deleted users within 30 days, or re-invite if the window has passed
