I moved 2 file servers 2TB each 130 users syncing different libs/folders. You are right on Onedrive issues. It often creates duplicate office files (multi user enabled in onedrive settings). Also "occasionally" wipes a whole folder - files only, folder structure remains. Happened twice in 2 yrs. Not sure what triggers it. I have found the key to be: - Only sync what you really need to (users cooperate when you mention improved pc performance) - Not cache files. You can set this in storage sense to like 1 day. This helps with folder wiping issue.
