There’s a new (March 2016) Volume Licensing Brief for Office 365.
This document has useful tables showing you all the Office 365 plans and what’s included in each one, as well as availability in the different channels. Then there’s an overview of the four flavours of USL that customers can choose from:
- Full USL (if you’re a new Online Services customer)
- From SA USL (if you’re transitioning from existing on-premises products with SA)
- Add-on USL (if you’ve got traditional licences and want to try the cloud), and a
- Step Up USL (if you want to go to a higher plan).
Finally, there’s a useful table showing the technical dependencies of some of the Office 365 services.
