Quick answer

Users missing or showing as Created/Unsynced after an HRIS sync usually have missing Employee IDs or mismatched emails. Correct them and re-run the sync.

Most likely fix: Match IDs and emails

How to fix it

Try these in order — the most common fix is first.

  1. 1. Match IDs and emails

    1. Add or correct Employee IDs in 15Five
    2. Make HRIS manager emails exactly match active 15Five users
    3. Run a manual sync

  2. 2. Use the preview

    1. Run a manual sync and review Validate & Review to see excluded rows
    2. Fix flagged rows, then complete the sync
    Did this fix it?

  3. 3. Allow time

    1. A full sync takes 10-15 minutes, up to a few hours for large companies
    2. The nightly 3:00 AM Eastern load re-applies existing HRIS data and does not fetch new changes; run a manual sync instead
    Did this fix it?

  4. 4. Workday: use the HRIS Connector

    1. The legacy Workday integration is no longer supported
    2. Set Workday up through the HRIS Connector (one-way, Workday to 15Five)
    Did this fix it?

  5. 5. Duplicate identifiers

    1. If two users share one identifier, contact 15Five Support to resolve it
