Outlook account login failed by authenticator

The error indicates that the authenticator (broker) app did not finish the sign‑in flow for the Outlook account.

To resolve this, complete the login directly in the authenticator or related broker app on the device, then retry signing in from Gmail/Outlook:

1. Open Microsoft Authenticator, Company Portal, or the primary Microsoft app on the phone.
2. Check for any pending sign‑in requests or prompts and approve/complete them.
3. After the sign‑in finishes successfully in that app, go back to Gmail/Outlook and try adding or logging into the Outlook account again.
4. If the password was recently changed and sign‑in still fails, contact the organization’s IT administrator to verify the account and reset the sign‑in if needed.

If the password is forgotten or the sign‑in cannot be completed in the authenticator app, the IT admin must help reset or unblock the account.
