In September 2014, Microsoft introduced Shared Computer Activation (SCA) so that Office 365 ProPlus could be installed on a server and then used by users with shared hardware.

There were restrictions on the server which was used – if it wasn’t a customer-owned server then it had to be a Service Provider server dedicated to the customer’s use, or Windows Azure.

From January 2016 the rules have changed, and now shared Service Provider servers are eligible too – as long as the partner meets the requirements to be an “Authorized SCA Partner”.

You can see this change detailed on page 19 of the January 2016 Online Services Terms document, and a great resource for both customers and partners is the SCA site here: http://bit.ly/23675Q0
