TaskRequestItem.MarkForDownload (Outlook)
Returns or sets an OlRemoteStatus constant that determines the status of an item once it is received by a remote user. Possible return values are olMarkedForCopy - Item is marked to be copied, olMarkedForDelete - Item is marked for deletion, olMarkedForDownload - Item is marked for download, olRemoteStatusNone - No remote status has been set, olUnMarked - Item is not marked.
This property gives remote users with less-than-ideal data-transfer capabilities increased messaging flexibility.
