Prior to any client connecting to a mailbox, the server MUST ensure that the DAF has been created for that mailbox as specified in [MS-OXOSFLD] section If a DAF for a mailbox has not been created or has not been found, then client-side rules and DEMs will not be processed by the client. The DAF SHOULD support notifications on its contents table object, as specified in [MS-OXCNOTIF].
