Final answer:
The statement is false as the MPSA offers a variety of Microsoft products and services, including different types of licenses besides M365 Full USLs.
Step-by-step explanation:
The statement that M365 Full USLs are the only M365 licenses available in the MPSA (Microsoft Products and Services Agreement) is false. The MPSA is a licensing agreement that provides a variety of Microsoft products and services, which includes different types of licenses besides the Full User Subscription Licenses (USLs).
These may include add-ons, step-ups, as well as other subscription plans catering to various needs of an organization. Thus, there are multiple options to choose from within the MPSA, offering flexibility to organizations in managing their licenses for Microsoft 365 and other Microsoft software.
