Installing on locally managed devices

Before installing Microsoft 365, an already installed Microsoft Office version (20xx/2016/2019) must be removed from the device. To do this, return your Microsoft Office licence via the self-service portal, otherwise it will still be subject to the quarterly rental fee.
