Properties by Namespace

Topic Last Modified: 2006-06-11

A namespace provides a unique name for every property in the Exchange store schema. For example, the namespaces urn:schemas:httpmail: and urn:schemas:mailheader: both contain properties named From. By prefacing the name of a property with the correct namespace, you can avoid collisions between properties with similar names. This section lists Exchange store schema properties that belong to each namespace.
