Can a passport issued in 2017 still be used?

It works. The validity period of a passport is ten years, or five years if the passport holder is under 16 years old. Therefore, no matter which year a passport is issued, its useful life is ten years. The passport issued in 2017 will not expire until 2027. As of February 23, 2023, the passport issued in 2017 can still be used.
