Locate your original software purchase receipt or check your email for the Microsoft order confirmation to quickly identify which version of Office you currently own.
Verify Your License Type in Your Microsoft Account
Log in to your Microsoft account online to officially confirm whether you own a perpetual license or an active Microsoft 365 subscription.
Your Microsoft account dashboard contains the definitive record of your software entitlements. Checking this page will instantly clarify whether you have a one-time purchase (like Office Home & Student 2021) or a recurring Microsoft 365 subscription.
Open your preferred web browser and go to the official Microsoft account login page (account.microsoft.com).
Log in using the email address and password that you used to originally purchase or activate your Office software.
Click on the 'Services & subscriptions' tab located in the top navigation menu of the dashboard.
Scroll down to view your active plans. If it says 'Microsoft 365', you have a subscription with multi-device and cloud benefits. If it lists a specific year (e.g., Office 2021), you have a one-time license for a single device.

Frequently Asked Questions
Can I upgrade my one-time Office license to Microsoft 365?
No, there is no direct upgrade path or discount applied for moving from a one-time perpetual license to a Microsoft 365 subscription. You will need to purchase the Microsoft 365 subscription separately at full price.
Does a one-time Office license expire?
No, a one-time Office license (such as Office 2021) is a perpetual license. It will never expire, and you can use those specific applications on that single device for as long as you want, though it will eventually stop receiving security updates from Microsoft.
Do I get OneDrive storage with a one-time Office purchase?
A one-time Office purchase does not include the premium 1TB OneDrive storage that comes with Microsoft 365. You only get the basic 5GB of free OneDrive storage that is included with every standard Microsoft account.
Can I install a one-time Office license on both my desktop and laptop?
No. A one-time Office license is strictly tied to a single computer (PC or Mac). If you need to install and use Office applications on multiple computers simultaneously, you must opt for a Microsoft 365 subscription.
