During the 2017 Six Nations Championship, Jones experienced his first defeat as England head coach when the team travelled to Dublin for their final game of the Championship, which they lost 9–13. Not only would a win have secured England's second consecutive Grand Slam but it would also have been a record 19th consecutive victory. Despite this disappointment, England were the overall winners of the Championship with wins over France (19–16), Wales (21–16), Italy (36–15), and Scotland (61–21). In June 2017, Jones took an inexperienced side for a two-test series in Argentina; the team included 18 uncapped players, eight of whom were less than 21 years old. Nevertheless, England won the series 2–0 with a 38–34 victory in the first test and a 35–25 victory in the second. England continued their form during the 2017 Autumn Internationals, winning all three of their tests: 21–8 against Argentina, 30–6 against Australia, and 48–14 against Samoa.
