Onedrive for Business new Generation Sync Client for Windows 2012 R2
Extend Onedrive for Business new Generation Sync Client for Windows 2012 R2 server
Office 365 Japan Support Team commented
I feel the same way. I really hope just like the same synchronization experience as the one seen in a different OS. I would say it is inconvenient if a modern generation sync client could not be applied to Windows 2012 R2 server.
If the old OneDrive for Business was working with Server2012R2 the new generation client should work as well.
This has a heavy impact on our users who use Server2012R2 RDS(Terminal Server) and use OneDrive for Business.
