A search for the standard model (SM) Higgs boson ($\mathrm{H}$) decaying to $\mathrm{b\overline{b}}$ when produced in association with a weak vector boson ($\mathrm{V}$) is reported for the following processes: $\mathrm{Z}(\nu\nu)\mathrm{H}$, $\mathrm{W}(\mu\nu)\mathrm{H}$, $\mathrm{W}(e\nu)\mathrm{H}$, $\mathrm{Z}(\mu\mu)\mathrm{H}$, and $\mathrm{Z}(ee)\mathrm{H}$. The search is performed in data samples corresponding to an integrated luminosity of 35.9~\mathrm{fb}^{-1} at \sqrt{s}=13~\mathrm{TeV} recorded by the CMS experiment at the LHC during \mathrm{Run~2} in 2016. An excess of events is observed in data compared to the expectation in the absence of a $\mathrm{H}\to\mathrm{b\overline{b}}$ signal. The significance of this excess is $3.3$ standard deviations, where the expectation from SM Higgs boson production is $2.8$. The signal strength corresponding to this excess, relative to that of the SM Higgs boson production is $1.2 \pm 0.4$. This result is combined with the one from the search for the same processes performed by the CMS experiment in \mathrm{Run~1} of the LHC (using proton-proton collisions at $\sqrt{s}=7$ and \sqrt{s}=8~\mathrm{TeV} with data samples corresponding to luminosities of up to 5.1~\mathrm{fb}^{-1} and 18.9~\mathrm{fb}^{-1}, respectively). The observed combined signal significance is $3.8$ standard deviations, where $3.8$ are expected from a SM signal. The corresponding signal strength, relative to that of the SM Higgs boson, is $1.06^{+0.31}_{-0.29}$.
