 When the cathedral chapter of Würzburg elected a new bishop in 1724, they rejected Friedrich Karl, due to the unpopularity of his late brother.Christoph Franz von Hutten was elected Bishop of Würzburg instead, and only upon the latter's death in 1729, Friedrich Karl succeeded him as Prince-Bishop of Bamberg.Johann Philipp Franz is buried in the "Schönbornkapelle" of Würzburg Cathedral.
