Heads up that Microsoft is disabling (as a default) Property Promotion within the SharePoint Sites used for OneDrive for Business in Office 365/SharePoint Online. I can definitely see why they are doing this as a default with OD4B considering it is being used much more like a DropBox (and synching) than as a typical SharePoint Document library with Metadata.
Heads up all the same.

As this seems to be the only place on the internet that mentions this (the other being an inaccessible technet article, google cache link:

To re-enable this setting it is the ‘ParserDisabled’ SPList property (same name on server and client.)
