Question: do jan and michael get back together the office

Answer: No, Jan is seen again in the fourth-season finale, in which she is revealed to be pregnant via artificial insemination. Michael goes to her Lamaze classes when Jan asks him to (where he apparently annoyed the teacher) and is incredibly excited to be there for the birth of ``their'' child. However, he is utterly deflated when Jan gives birth to her daughter Astrid without him there, and when Jan reluctantly lets Michael spend time around her, Michael sadly recognizes that he feels no connection at all to Astrid and that he is no longer holding onto feelings for Jan. Jan also insists Michael not go out with Holly, leading Michael to promptly and successfully ask Holly out on a date.
