I am aware that there are various protocols by which MS Exchange exposes access to services - including:
- EAS : Exchange Active Sync - A proprietary protocol that appears to be the default option for access to Exchange from mobile devices.
- EWS : Exchange Web Services - An openly documented SOAP protocol- a standard Web Service with a WSDL definition.
- Exchange Outlook Anywhere (also known as RPC/HTTP) ...now deprecated in favour of MAPI over HTTP?
If I only have access to Exchange Web Services, for a particular Exchange Server, is there any way to access those services using Outlook Mobile (on Android, iOS or Win-10-phone)?
If direct access is not viable, is there such a thing as an Exchange-Active-Sync (client-side) to Exchange-Web-Services (server-side) bridge?
If no bridge between EAS and EWS exists, is it feasible to deploy Outlook Web App to present EWS services in web browsers on phones? (Essentially, can Outlook Web App be configured to, exclusively, communicate with Exchange using EWS via a Web Proxy?)
If none of the above are feasible, can I use Outlook (on a Windows laptop) to connect to the EWS Service?
