Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi Deborah,
My name is Igor, it's a pleasure for me to help others and I'll try to help you. I am merely a fellow user trying to provide insight and information that may be helpful to others.
Seems this was either misunderstanding or misleading you. There is no "lifetime subscription" at all.
Office may be sold as one-time purchase or a subscription. One-time purchase means Office 2016, or Office 2019, or any late Office version. User pays for a licens once and may use this product forever.
Subscription (Office 365 and later Microsoft 365) means the use pays monthly or yearly during all period of Office using.
Can you tell the full name of purchased product?
