Microsoft Exchange Connectivity Architecture based on WebDAV Protocol
Microsoft Exchange server 2000, 2003 and 2007 support Web Distributed Authoring and Versioning (WebDAV) protocol via Outlook Web Access (OWA) to access a Mailbox on a Exchange server.
Microsoft Exchange server 2007 has limited features to support WebDAV. Refer to SAP Note 1368473 for details.
Transport
The WebDAV transport consists of only a Java component that runs on the portal server. The WebDAV transport and DAVXchg transport are used interchangeably but they both mean the same.
Architecture and Deployment Requirements
The figure below illustrates architecture and deployment requirements.
- The Java component makes an HTTP(S) request to the Exchange server via OWA. It passes user credentials using basic authentication.
- The Exchange server retrieves the relevant data and returns it to the Java component as an XML stream.
