Final answer:
The question references a character from the TV show 'The Office' who graduated high school with Michael, but the show is fictional and does not provide a clear answer.
Step-by-step explanation:
The member of the office who graduated High School with Michael is not specifically identified in the question, but appears to be a reference to the American television series 'The Office.' As such, this is a fictional storyline and not a historical or factual event tied to a real person.
The show, which has a comedy genre, involves various characters with diverse backgrounds, and the specific detail about who graduated with Michael is not a prominent plot point in the series.
