Looking to find out if anyone has documented fairly current state of what the impacts are of using O365 services and apps (SPO, Teams, Planner, PowerApps, Forms, Flow, etc.) if an organization does the AD to AAD integration for SSO through ADFS, but does NOT move the O365 user's mailboxes up to EOL (hybrid) and/or doesn't hybrid Lync on-prem to Skype for Business cloud?
