Getting Started with Office 365 and EMS for Microsoft Cloud Solution Providers


The Microsoft Cloud Solution Provider (CSP) program was released in July 2014 t to provide a scalable, flexible partner program. Designed to deepen customer relationships and expand business opportunities, the CSP program allows partners to:

  • Own and control billing
  • Sell combined offers and services
  • Deliver direct provisioning, management and support

To achieve those capabilities, CSP partners need to integrate their backend systems and business processes with various Microsoft cloud services and processes. Once integration has taken place, CSP partners then have the ability to directly provision, manage and support clients within the Microsoft Office 365, Microsoft Azure, Dynamics CRM, and Enterprise Mobility Suite (EMS) product offerings.

The goal of this document is to help CSP partners to quickly implement Enterprise Mobility Suite (EMS) solutions for clients who have Office 365 E3/E5 or Office 365 Business Premium.

This document provides guidance to support the extension for CSPs looking to enable clients with subscriptions.


The scope of this document is to provide the necessary guidance to extend an existing Office 365 deployment to include EMS.

The focus of this document is on the implementation guidelines for extending a deployment to include EMS, but not how to configure EMS.
