My company currently uses O365 and we sync our AD from on premises to Azure. This company is branching off and forming a new company. I am looking for help on how to get this new company running Azure AD only, (they will have O365 as well) and more specifically how do I get that domain to do a trust with my on premises domain? Ex: current company is abc.com running AD onsite and using O365, new company xyz.com spinning off from abc.com, will not have on premise AD instead will use Azure AD and I need abc.com to trust the Azure AD domain xyz.com
