Yes, I was able to follow your instructions and set this up. Not sure if it matters, but are an on-premise EX2013/EX2010 hybrid shop right now. But everything I did, I did it on the EX2013 side. Also, I didn't have to do step 2 as I logged into a VM as user U and setup the mail profile with Outlook 2010. Instead of prompting me for a username/password, it just used my logged in credentials because user U has full access to the resource mailbox R. If you wanted, you could also add user U directly to resource mailbox R directly with EMS to see if that works:
