Introduction to PSfP support for EAS licensees


Senior Application Development Managers, David Huang and Sheldon Ledbetter spotlight support options for EAS licensees


Exchange ActiveSync, also known as EAS, is a development protocol requiring purchase of Microsoft Licenses. Almost all major mobile device manufacturers who use Microsoft EAS API to develop their email, calendar, and messaging applications to interact with Exchange Servers need licenses from Microsoft. We refer to these Original Device Manufacturers as the “EAS Licensees”.  Frequently, these partnerships benefit from a deep support relationship our customers often establish through Premier.

imageIn Microsoft’s Premier Support for Partners (PSfP) business, Application Development Managers have experience in working with EAS Licensees and are managing their contracts for both advisory and reactive work. Examples of EAS support issues are: Certificate-Based Authentication (CBA) architecture and requirements, Exchange Web Services (EWS) for online interactions (separate API), Calendar synchronization with Add/Delete/Change events, Meeting Organizer and Meeting Delegates, Contact duplications in iOS or Android, Meeting attachments forwarding, Android auto-configurations, EAS password policies, EAS biometric policies, EAS RMS (Right Management Service) consultation, and many more. Under this support model, we also provide consultation and the early adoption program for next-generation Exchange Server EAS specifications.

For several years now the Microsoft product group has further integrated the API of EAS for Exchange with EAS for Hotmail, and is starting to support Hotmail/Outlook Express issues for EAS Licensee Partners. This is significant in boosting our EAS supportability in Office 365 issues including OAuth (Open Standard of Authorization) version 2.0 for O365 accounts of Exchange and Hotmail via Outlook (REST API).  Premier Support relationships are often instrumental in staying informed on the latest development, driving feedback, and receiving critical support with the technologies most important to your business.


Premier Support for Developers and Partners provides strategic technology guidance, critical support coverage, and a range of essential services to help teams optimize development lifecycles and improve software quality.  Contact your Application Development Manager (ADM) or email us to learn more about what we can do for you.
