The LHCb Outer Tracker is a gaseous detector covering an area of $5\times 6m^2$ with 12 double layers of straw tubes. The performance of the detector ispresented based on data of the LHC Run 2 running period from 2015 and 2016.Occupancies and operational experience for data collected in $p p$, pPb andPbPb collisions are described. An updated study of the ageing effects ispresented showing no signs of gain deterioration or other radiation damageeffects. In addition several improvements with respect to LHC Run 1 data takingare introduced. A novel real-time calibration of the time-alignment of thedetector and the alignment of the single monolayers composing detector modulesare presented, improving the drift-time and position resolution of the detectorby 20\%. Finally, a potential use of the improved resolution for the timing ofcharged tracks is described, showing the possibility to identify low-momentumhadrons with their time-of-flight.
