We present a measurement of electron-neutrino interactions from the Fermilab Booster Neutrino Beam using the MicroBooNE liquid argon time projection chamber to address the nature of the excess of low-energy interactions observed by the MiniBooNE collaboration. Three independent electron-neutrino searches are performed across multiple single-electron final states, including an exclusive search for two-body scattering events with a single proton, a semi-inclusive search for pionless events, and a fully inclusive search for events containing all hadronic final states.
