Purchase licenses
Licenses for Microsoft 365 can be purchased through the Microsoft 365 admin center at https://admin.microsoft.com or via a Microsoft partner. Each user within your organization needs a valid license to access Microsoft 365 services. Administrators can assign, reassign, or remove licenses as needed.
