The EWS Managed API provides a simple and full-featured interface for developing and extending client applications that use EWS. You can use the EWS Managed API to access EWS in Office 365, Exchange Online, and versions of Exchange starting with Exchange Server 2007 Service Pack 1 (SP1).
Note
The EWS Managed API is now available as an open source project on GitHub. You can use the open source library to:
-
Contribute bug fixes and enhancements to the API.
-
Get fixes and enhancements before they are available in an official release.
-
Access the most comprehensive and up-to-date implementation of the API, to use as a reference or to create new libraries on new platforms.
We welcome your contributions via GitHub.
The EWS Managed API provides developer-friendly abstractions of XML messages, XML serialization, and the creation of the HTTPS requests and responses that are exchanged between the client and server. Because the EWS Managed API is easier to use, if you’re a .NET Framework developer, we encourage you to use it over autogenerated proxies to develop EWS clients.
