We are using SP2016 standard on-premise. We can setup user profile import successfully and all users are imported at first time setup. However when I check the timer job
User Profile ActiveDirectory Import Job the last run time is always "N/A". If I click
Start Profile Sync it seems nothing happens. The status is always Idle even though I refreshed the page.
The problem is I found some users have their Display Name updated. But in user profile their account is still using the old value.
Could you advise what could be wrong?
