Can service providers in the SCA Program only host Office 365 ProPlus, Project Online Professional and Visio Pro for Office 365 if the licenses were purchased through CSP?

A service provider in the SCA Program must be a valid and existing Direct (1-Tier) Cloud Solution Provider (CSP) and a SPLA provider. However, the end customers deploying SCA through a hoster do not necessarily have to purchase their Office 365 ProPlus, Project Online Professional and Visio Pro for Office 365 licenses through CSP. If the licenses are for Office 365 ProPlus, Project Online Professional or Visio Pro for Office 365 (and not a perpetual/on-premises version of Office), it does not matter what channel the license was purchased through.
