We shipped support for installing the OneDrive app on an SD card, but any files taken offline still go to internal storage. We do have plan to enable offline files to be stored on SD card. I’ll update status as we get further along.

Welcome to 2019.
This needs to be fixed. As the person below me stated this works for individual files manually but it needs to be done at the folder level, and have an automatic option for all selected folders, all the time, to an SD card in any android phone.
Major hole in my new cloud strategy, not just music is affected. I have several files I need to be able to easily open on Android, and PC. Get this done. sad really.
