You will have leftovers. That’s the ham’s noble purpose: to feed an army for a week.
Reheat leftovers to 165°F if you’re immune-compromised or nervous. Otherwise, 140°F is fine for ham soup, sandwiches, or ham-and-cheese casserole.
Funny rule: If your ham smells like a gym locker, don’t eat it. If it smells like sweet, salty pork, you’re golden. Trust your nose more than the clock.
