robocopy para Drive File Stream falha no PowerShell, mas não na linha de comando Erro 5

Question

Quando executo o robocopy em um prompt de comando do administrador, ele é executado com êxito.

C:\Users\StoreMgr>robocopy "C:\Users\Public\Documents\Intuit\QuickBooks Point of Sale 12.0\Data\Paracept" "G:\My Drive\Backup" qbpos1.db

Eu executei sem parâmetros no PowerShell com os mesmos erros

Executando o PowerShell como administrador em todos os casos

Robocopy C:\Users\Public\Documents\Intuit\QuickBooks Point of Sale 12.0\Data\Paracept G:\My Drive\Paracept qbpos1.db
