Followed these steps to configure Recycle Bin:
Web browser: Log into control panel via:
http://wdmycloudex2100
Shares: Pick a share to add a Recycle Bin to:
Under Share Profile: Active share: Recycle Bin ON.
Now under your Network Places the Recycle Bin should show up.
However, deleted files were not going to the Recycle Bin.
I rebooted the EX2100 and now deleted files show up in the Recycle Bin.
I hope this helps someone else. I could not find an answer anywhere so had to invent my own,
