We have begun to migrate user contents from a file share to their individual OneDrive for Business account. We have used GPO to handle settings per Microsoft guidance. If a user also has a personal OneDrive account, we can install, connect and sync with no issue; however, if a user opens a doc in OneDrive personal they are prompted to sign in. When they go and sign in they receive a feature has been disabled by admin alert. Review GPO settings and do not see where we are blocking OneDrive personal and we are out of ideas. Opened a support case with O365 and they said they could not help because it is a OneDrive personal issue. Suggestions?
