Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
There is no such thing as a "lifetime" subscription of Microsoft Office. The person who promised it was a scammer. Office subscriptions require that you pay regularly, yearly or monthly, for your right to use the Office applications.
If you want a one-time payment product, you can get Microsoft Office Home 2024, which is a perpetual license. It is for one user and one computer (PC or Mac). No mobile apps are included and you won't get the classic Outlook.
