Office 365 serves ut Office Pro Plus and Microsoft has started rolling out an updated Version With support for Shared Computers. Meaning Terminal Services and Computers shared with different users login in to the same computer.
This has been a problem for licencing and Connection to OneDrive, OneDrive for Business and SharePoint Libraries. It didn’t secure the Access to the Resources distinguished from each using the same computer/terminal service.
Requirements as of today to be applicable for this update:
You as the enduser company need to own the physical hardware underneath the servers, so this will be true for Companies housing their own servers and probably for Companies owning, but housing the servers at providers datacenter.
But it cannot be shared With other customers, as they wouldn’t own the physical hardware.
So for multitenant RDS/TS it will not be applicable at the moment, but hosters for this still need to buy SPLA Licenses, but the customer can’t buy a lower Office 365 Plan without Office Pro Plus. I wouldn’t recommend it unless the hoster has a easy way to distribute the software and also Office 365 gives the endusers five installations at the same time.
