At the moment each department has a NTFS share and when they login we use group policies to map this to S: (for "staff").We want to move to using Office 365 Sharepoint and instead of an NTFS share each department will have its own SharePoint library eg. "Physics". Windows 10 1709 allows the user to Sync a library and it will then appear in Windows Explorer. This is great, unfortunately admins cannot add the library using Group Policies or Powershell. I don't know how I am going to do the mappings for 2000 users :
