Likely cause

What is usually actually broken

The lookup source is incomplete, stale, or temporarily unavailable, so you do not yet have enough evidence to trust the result.

Next steps

Do these before you resend

  1. Pause the resend and treat the lookup as advisory.
  2. Confirm the full scheme-plus-value pair you expect to use.
  3. Escalate with evidence if the provider and live lookup disagree.
FAQ

What people ask right before they get blocked

Does inconclusive mean the recipient is unavailable?

No. It means the lookup did not give you enough confidence to treat the answer as final.

What should I gather before contacting support?

Bring the exact participant ID, the lookup result, and the last provider symptom so support can separate route problems from source-system issues.
