Allow the programatic management of OneDrive permissions
We have retention policies on OneDrive for legal reasons.
We sync from an on-prem AD so when someone leaves and then returns after their account has been hard deleted from AzureAD,
OneDrive retains the old object GUIDS but only displays the display name in the SharePoint GUI.
This makes it very hard to proactively manage when you have several hundred staff/student turnover each year and no way to identify these sorts of errors and correct before it becomes a problem.
