FileDownloadInfo.UniqueId Property

Definition

The ODSP/OneDrive identifier for the file. Useful for correlation, dedup and logging, but not for retrieval: the Graph fetch resolves bytes from the attachment's contentUrl through /shares, and this value arrives as a GUID, which is a SharePoint listItemUniqueId shape rather than a Graph driveItem.id.
