Last month I wrote a post on licensing Office for a Remote Desktop Environment. In that post, I covered the basics and recommended you purchase a volume license of Office for the endpoint devices that are accessing the remote desktop session on a terminal server. I stressed that you need to license the device, not the user.
But what about Office 365? In Office 365, you purchase a subscription for each user, not each device. So how does that work when your user needs to access a remote desktop session and fire up Office on the server? Do you still need to purchase a volume license of Office to cover that device?
Unfortunately there is not a simple “yes” or “no” answer to that question. (Why can’t licensing ever be simple?!) The answer will depend on what subscription plan you signed up for. Some of the Office 365 plans include the right to access Office on a terminal server, but some of them don’t. Here’s what to look for …
The permission you need is called “Desktop Virtualization.” Here is Microsoft’s description of that Office 365 feature in a TechNet post:
Desktop virtualization
Customers can use Remote Desktop Services (RDS), a role in Windows Server, to provide a centralized server on which they can install Office. Users log on remotely to this centralized server to run Office. Organizations can also use Remote Desktop Services with Hyper-V to deploy virtual desktops to users. To deploy Office 365 ProPlus by using RDS, you need to use shared computer activation. To learn more, see Overview of shared computer activation.
To see which Office 365 plans include this feature, you will need to consult one of the following resources. There is an interactive chart available. Or you check out the table Microsoft posted. Here is the status of the current Office 365 subscription plans (the column marked “Office Professional Plus 2013” refers to the volume license of Office):
So currently, only the following plans include the right to access Office on a terminal server:
If you have a user who is subscribed under any of those plans, then that user can access Office in a remote desktop session from any device. That device does not need a volume license of Office since the permission is assigned to the user anywhere he or she goes.
To sum up, if you have someone who needs to access Office in a remote desktop session on a terminal server, you have two options:
In light of this, let me update the whiteboard illustration I used in my last post. In the image below, the first user has no Office 365 subscription, but is using a device that has an Office volume license assigned to it. The volume license gives the user the right to access Office on the terminal server. The second and third users are using devices that do not have volume licenses assigned to them, but the users have Office 365 subscriptions that include the “desktop virtualization” feature. So their Office 365 subscriptions provide them with the right to access Office on the terminal server. Please note that all the users still need a Windows Server User CAL and an RDS User CAL.
