Setting Multivalued Properties (WebDAV)
Topic Last Modified: 2006-06-12
The following WebDAV PROPPATCH Method request sets the expected-content-class Field of a folder to urn:content-classes:message and urn:content-classes:item content classes and the custom content class urn:contentclasses:myclass1.
See Constructing Exchange Store HTTP URLs and Authentication and Security Using WebDAV for more information.
