Use Microsoft enhanced client or proxy (ECP) with EAA

SAML IdP with Microsoft enhanced client or proxy

Microsoft Office 365 allows you to manage Microsoft Exchange Online with the enhanced client or proxy (ECP). Enterprise Application Access (EAA) works with ECP to authenticate users through the EAA SAML IdP. In this setup, Microsoft Outlook acts as a normal dummy client so that Office 365 Azure-based service providers (SP) can interact with the EAA SAML IdP to authenticate the user. Certain desktop and mobile SaaS applications can use ECP to sign on to the SP, for example MacBook Mail client or Gmail app.
