Hi Scott,
Thanks for your reply.
I read the article and its mentioned O365 ProPlus. We subscribed to O365 Business Premium.
Basically, i created OneDrive appstacks. Using command, installed onedrive /allusers and assigned appstack.
Login as user, i can see OneDrive app and click to launch the app but it won't launch.
What can i do to have a successful launch of the app?
