Frequently Asked Questions

Why does Microsoft push Microsoft 365 when I bought Office 2021?

Microsoft strongly prioritizes its subscription model (Microsoft 365). As a result, they use a unified installation portal that defaults to displaying Microsoft 365 branding, even when you are accessing a perpetual (one-time purchase) license.

Will I be charged for a subscription if I see Microsoft 365 during installation?

No. As long as you do not explicitly opt-in to purchase or start a Microsoft 365 trial, simply downloading your Office 2021 product from the 'Services and subscriptions' page will not incur any recurring subscription charges.

How do I know if I actually installed Office 2021 or Microsoft 365?

Open any installed application, such as Word or Excel. Click on 'File' in the top left corner, then select 'Account' (or 'Help'). Under 'Product Information' on the right side, it will clearly state whether you are running 'Microsoft Office Professional 2021' or 'Microsoft 365'.

What should I do if the installation still downloads Microsoft 365?

Ensure you clicked the 'Install' button specifically next to your Office 2021 product in your Microsoft account. Pay close attention to the installation pop-up window; you may need to click 'Other options' or check a secondary drop-down menu below the language selector to force the perpetual version to download.
