 The king, who admired his preaching, promised him the prebend of Winchester, vacated by the promotion of Thomas Ken to the bishopric of Bath and Wells; it proved, however, to be in the gift of the lord keeper, and Thomas Fox obtained it.In November 1684 Manningham was made preacher at the Rolls Chapel, and from about 1689 to 1692 was head-master of Westerham grammar school, Kent.He subsequently became rector of St. Andrew, Holborn, on 8 September 1691; chaplain in ordinary to William III and Mary II; canon at St George's Chapel, Windsor on 28 January 1692-3 (until 1709); rector of Great Haseley, Oxfordshire, 1708; and dean of Windsor on 26 February 1709.
