Microsoft 365 Personal - subscription licence (1 year) - 1 person

For Microsoft 365 plans, internet access is also needed to manage your subscription account, for example, to install Office apps on other PCs or to change billing options. Internet access is also required to access documents stored on OneDrive, unless you install the OneDrive desktop app https://www.microsoft.com/en-us/microsoft-365/microsoft-365-for-home-and-school-faq

You should also connect to the internet regularly to keep your version of Microsoft 365 up to date and to benefit from automatic upgrades. If you don’t connect to the internet at least every 31 days, your apps will go into reduced functionality mode, which means that you can view or print your documents, but you can’t edit them or create new ones. To reactivate your apps, simply reconnect to the internet.

You don’t need to be connected to the internet to use the Office apps, such as Word, Excel, and PowerPoint, because the apps are fully installed on your computer.

Your Microsoft account is the combination of an email address and password that you use to sign in to services like OneDrive, Xbox LIVE, and Outlook.com. If you use any of these services, you already have a Microsoft account that you can use, or you can create a new account. Learn more about a Microsoft account https://account.microsoft.com/account/Account.

As part of signing up for a trial or purchasing Microsoft 365, you’ll be prompted to sign in with a Microsoft account. You must be signed in with this account to install and manage your Microsoft 365 subscription, or to use some subscription benefits, including OneDrive storage.
