Shared computer activation can be enabled by editing the configuration XML file (part of the Office Deployment Tool) to include the following lines:
<Display Level="None" AcceptEULA="True" /> <Property Name="SharedComputerLicensing" Value="1" />
Any licensed user who subsequently uses the computer to run Office 365 Pro Plus will be able to (and will be granted a temporary token). The temporary token does not count against the user’s 5 computer limit, and a user can have a ‘reasonable’ number of tokens on various shared computers.
