Microsoft announce that Shared Computer Activation will be available for Office 365 Business when it’s acquired as part of a Microsoft 365 Business licence.
A Microsoft 365 Business User SL only allows the installation of Office 365 Business on up to 5 PCs, but with SCA enabled a user may access Office 365 Business running (for example) in an RDS environment and it doesn’t count against that 5 PC limit. The roll out of SCA for Microsoft 365 Business customers began on 30 April, 2019 and is expected to take a couple of months.
