OLE DB Type

Remarks

This property, along with the urn:schemas-microsoft-com:exch-data:comprogid, identify a COM class that may be used to handle or process items of this content class. This mechanism is similar in intent to the MAPI Forms registry, where the PR_MESSAGE_CLASS has an associated form CLSID that can render and process the item for the user.

Use of this property is application specific and does not affect the operation of a Web Store.
