(covers information from an alternate timeline)
In that year, The Doctor inquired with Director Okaro as to the whereabouts of Admiral Janeway, under the impression that she was on a classified mission, but was assured that Janeway hadn't been involved with any classified work since she started teaching at Starfleet Academy. When The Doctor told Reginald Barclay this, Barclay suggested that the director might have been trying to throw him off the scent.
This timeline was later negated when Janeway traveled back in time to 2378 and assisted the crew of the USS Voyager with returning to the Alpha Quadrant sixteen years earlier than they would have without the admiral's assistance. (VOY: "Endgame")
