Power BI Error:
AADSTS50014, Guest user not yet accepted invitation
What does this error mean?
A B2B guest user exists in a pending state and hasn't redeemed their invitation, so sign-in to the tenant fails.
Common causes
- 1User was invited as a B2B guest but never clicked the invitation redemption link
- 2Invitation email was filtered, expired, or sent to a stale address
- 3Application is pointed at the wrong tenant — the signed-in user exists elsewhere, not in this directory
- 4Guest account was created via API/script without triggering an invitation flow
- 5Cross-tenant access settings or external collaboration policy blocks redemption from the user's home tenant
How to fix it
- 1In the Microsoft Entra admin center, open Users → External Users and locate the guest by email; confirm the 'Invitation state' is Pending Acceptance
- 2Resend the invitation: select the user → Resend invitation, or generate a new redemption URL via the Invitation Manager / Graph API and share it directly with the user
- 3Have the user open the redemption link in a private browser session and complete consent; verify their Invitation state flips to Accepted
- 4If the user shouldn't be a guest at all, verify the application is configured for the correct tenant (check the authority URL / tenantId in the app's auth config) — AADSTS50014 often means the app is targeting the wrong directory
- 5Check Cross-tenant access settings (External Identities → Cross-tenant access settings) to confirm inbound collaboration from the user's home tenant is allowed
