I am migrating our local document storage to Office 365 SharePoint document libraries.
Part of what I've been asked to do is migrate documents owned by HR to a document library, but access to this library must be tightly controlled.
Ideally what they want is only the owner(s) of the site/library can grant access to it, and Office 365/SharePoint Admins can't access or grant access.
Is this possible, so far I haven't found a way?
