Office Pro Plus has been available via Office 365 for a while but using it via an RDS server has never been allowed…until now.
With the recent update to Office 365, Microsoft have relaxed the licensing rules to allow RDS use of Office 365 licenses. Under “Installation & Use Rights” on page 82 of the January PUR:
Each user may also use one of the five activations on a network server with the Remote Desktop Services (RDS) role enabled
and from the March Product List:
Media Eligibility with Remote Desktop Services (RDS)
If the user to whom you have assigned an Office 365 ProPlus license uses the software on a network server with RDS role enabled, in lieu of installing a copy of the software provided with Office 365 ProPlus on one of the five permitted devices pursuant to the Product Use Rights for Office 365 ProPlus, that user may 1) install one copy of the Office Professional Plus 2013 software on a network server and 2) access the Office Professional Plus 2013 software from any device. Upon termination of your Office 365 ProPlus subscription you must uninstall Office Professional Plus 2013 software from the network server.
I’m glad they’ve done this as it makes the messaging of “same product, different delivery method” a much truer statement and reduces any possible confusion for customers.
Cloudy with a chance of Licensing 
Yes, but what media and license do you use to install on the RDS?
Exactly the issues here is still the same problem, no media or license for RDS.
