When you want to migrate an older environment to Office 365 and OneDrive, you might miss the OneDrive GPO settings. Unfortunately Microsoft hasn’t release the download of the ADMX files. You will need to grab them manually from a recent Windows 10 machine, and import them in the right location.
Since I like to simplify things, I thought it might be convenient to create a prepared ADMX ZIP file with all necessary files, ready for extraction. So here is a link to download OneDrive ADMX files. Just simply extract the proper folders to the following location:
Local Domain Controller store: C:\Windows\PolicyDefinitions\
Central Active Directory store: \\<your domain>\sysvol\<your domain>\Policies\PolicyDefinitions\
