Using Microsoft 365 Basic Alongside Office 2021
You can safely run both products together to maximize your desktop productivity and cloud storage without software conflicts.
Microsoft 365 Basic and Office 2021 serve entirely different functions and are designed to work together smoothly. Office 2021 provides the locally installed, permanent desktop applications like Word, Excel, and PowerPoint. Conversely, Microsoft 365 Basic primarily offers enhanced cloud services, such as 100 GB of OneDrive storage and ad-free Outlook email on the web.
Because Microsoft 365 Basic does not attempt to install newer desktop versions of the Office apps, it will not overwrite or conflict with your existing Office 2021 installation.
Log in to your Microsoft account dashboard, navigate to your purchased products, and download your Office 2021 desktop applications.
Open the OneDrive desktop client on your computer and sign in with the Microsoft account associated with your Microsoft 365 Basic subscription to sync your 100 GB of storage.
Launch any Office 2021 application (such as Word), click on 'File', navigate to 'Account', and ensure your Microsoft account is connected under the 'Connected Services' section. This allows you to save and open files directly from your Microsoft 365 Basic OneDrive storage.

Frequently Asked Questions
Does Microsoft 365 Basic include desktop apps like Word and Excel?
No, Microsoft 365 Basic only provides access to the web and mobile versions of Office apps. To use desktop applications, you need a separate product like Office 2021, Microsoft 365 Personal, or Microsoft 365 Family.
Can I save Office 2021 files directly to my Microsoft 365 Basic OneDrive storage?
Yes. By signing into your Office 2021 desktop applications with the same Microsoft account you use for your Microsoft 365 Basic subscription, you can seamlessly save and open documents directly from your 100 GB OneDrive cloud storage.
Will subscribing to Microsoft 365 Basic override my Office 2021 permanent license?
No. Because Microsoft 365 Basic is a cloud service and does not install newer desktop software, your Office 2021 applications and its permanent license will remain fully intact and functional.
