How Do I Change My Microsoft Office 365 Product Key?

  • Microsoft Office 365 is an integrated set of features to create projects, presentations, keep records, and customize them with various options. It consists of apps like Microsoft Office, Excel, PowerPoint, OneNote, etc. You can download setup Microsoft Office 365 for all these products online or from certified stores.


    If you have bought Office Home & Business, Home & Student, Professional, or other applications, for use on multiple PCs, then you might face some issues. When you try to install the same Office subscription on different PCs, it fails, enough though you have purchased it for multiple devices. This happens due to the Install button which has different product key for different devices. So if you try to enter the same product key on different devices, it will not allow installation.


    To fix this issue, you need to change the product key for other connected PCs in which you have installed the software. In the latest version of Office 365 2019 or 2016, follow the given steps below-

    • Open your computer and then your preferred browser.
    • Go to Microsoft Office official website or open the app.
    • In the app, select the File menu and then choose Account option.
    • Check the Product Information and under it, select Change License button.
      • If there is no option like this, upgrade your app to the newest version with required updates.
    • If you have already signed in to your account, choose Use a different account. Then enter the product key by choosing the correct option.
      • If you did not log in to your account, click Enter product key instead.
    • Type in your product key/serial number and then tap Install this product instead.
      • If the product is never used before then follow the prompts to complete the process.
