A company has an existing Microsoft 365 environment. The company wants to purchase an add-on to its existing subscription and requires that: - The add-on purchase is linked to the subscription. - The

Full USLs (User Subscription Licenses) are complete, independent licenses that are not dependent on an existing subscription and would not automatically cancel if the base subscription is cancelled.

Standalone add-ons in Microsoft 365 are specifically designed to be purchased in addition to an existing base subscription and are directly tied to that subscription.
