Assign or Unassign Licenses for Microsoft Office 365 for Business

In Office 365 for business, users need licenses to use Outlook, SharePoint Online, Lync Online, and other services. As a global or user management admin, you can easily assign licenses to new users when creating new accounts, or to users with existing accounts. To free up licenses that can be assigned to other users, you can also unassign licenses that users no longer need when people leave the organization. To reduce the number of user licenses for your Office 365 subscription, see Remove licenses from your Office 365 for business subscription.
