Now it is understood that a number of Championship and League One clubs are pursuing his signature, while interest has also been shown from the Middle and Far East.
Birmingham and Wigan Athletic are heading the chase and have made moves, and now Lowry is weighing up his options.
Lowry joined Orient last summer after departing Millwall.
He had spent the two years prior to that with the Lions, having moved to the Den after failing to make the breakthrough at Aston Villa.
His time with the Premier League outfit delivered just three competitive appearances, with most of his experience picked up during loan spells at Plymouth Argyle, Leeds United, Sheffield United and Millwall – prior to his permanent switch.
