Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
As an individual user, you should purchase Microsoft 365 Personal (if you want a subscription) or Microsoft Home & Student (if you prefer a one-time payment license). Note that Home & Student does not include Outlook; Home & Business does include Outlook, if you need that program.
