にて / をもって / を限りに
Naming the means, or the effective date, in an official announcement.
Noun をもって vs Noun にて: Use をもって: 本日をもって終了, 書面をもって通知する. にて marks where something takes place, a stiff old-fashioned で. Both are ceremonial, but only をもって can carry a means or an effective moment.
Announcing that something ends at a given point.
Noun を限りに vs Noun をもって: を限りに specifically marks a cut-off: after this, no more (今年を限りに引退する). をもって can mark the same date neutrally, so it is the one to use when the point is when something takes effect rather than when it stops.
