Internet access is required for downloading and enabling all the new Office
suites releases and all Office 365 subscription plans. Internet access is also
required for Office 365 plans to control your subscription account, e.g. to
install Office on other PCs or to change billing options. Internet access for
documents stored on OneDrive is also required, unless you install OneDrive
desktop app.To keep your Office edition up-to-date and benefit from automatic
updates, you should also connect to the Internet regularly. When you do not
connect to the Internet at least every 31 days, your applications will go into
reduced functionality mode, which means you can access or print your documents,
but you will not be able to update or build new documents. Simplify reactivating
your Office software by reconnecting the Internet.

To use the Office software, such as Word, Excel, and PowerPoint, you don’t need
to be linked to the Internet because the programs are completely installed on
your computer.
