AADDS and SidHistory

It appears that the SidHistory arrives in AADDS from AzureAD using the onPremiseSecurityIdentifier. attribute. The problem I have is on a particular customer that doesn't have an OnPrem AD, I want to create shares from a file server in AADDS and allow laptops connected to AzureAD access. Without the sid history from accounts created in O365 (Azure AD), I cannot grant access.
I also cannot access the onPremiseSecurityIdentifier attribute within o365 as a get around to allow the one way sync to AADDS. Any ideas?
