APM seems like the way to go, if you add authentication before traffic reaching the Exchange server you have a good protection.

 

it remains kinda unclear in which path the attacks focus, this website suggests one. but things move quickly probably.

      Thank you boneyard :) Great articles

      We do have the APM along with 2fa on the OWA

      we'll check also the ASM option

      I saw also that DevCentral published ASM template to have OWA in blocking mode from day one
