I had purchased a Microsoft Office 2021 license, which was installed on my desktop, that has unfortunately crashed a few months ago. I would now like to use the same product key on my new desktop. However, Office is not allowing me to activate the key on this new device. I am also unsure whether the license was registered with any email ID."

    Hello,

    Microsoft’s official documentation states that a one-time purchase version of Office (such as Office 2021) is usually licensed for installation on only one device, but it can be transferred to another computer under your ownership. Generally, there is a 90-day transfer restriction, but if the hardware fails (for example, if your computer breaks down), you can transfer it earlier.

    First, confirm which type of purchase your Office 2021 belongs to.

    • If it is a Retail version (commonly purchased via a product key card from a store or directly from the Microsoft Store), it can usually be transferred.
    • If it is an OEM version (preinstalled on a branded computer), in many cases it is tied to the original machine and cannot be transferred. Microsoft distinguishes between these different licensing methods.

    To transfer your Microsoft Office 2021 product key from a crashed computer to a new desktop, you can follow these steps:

    1. Check License Type: First, confirm that your Office 2021 license allows for transfer. Retail licenses typically allow you to transfer the software, while OEM licenses are tied to the original hardware.
    2. Deactivate Office on Old Device: If possible, you should deactivate Office on your old device. This can sometimes be done through your Microsoft account if the license was registered there. If you cannot access the old computer, you might need to contact Microsoft support for assistance.
    3. Install Office on New Device: On your new desktop, download and install Microsoft Office 2021. You can do this from the official Microsoft website or through the installation media if you have it.
    4. Activate Office: During the installation or the first time you open an Office application, you will be prompted to enter your product key. Enter the product key you have.
    5. Troubleshooting Activation Issues: If you encounter issues activating Office on the new device, you can refer to the troubleshooting steps for product key errors, which may provide solutions for common activation problems.

    If you are unsure whether the license was registered with any email ID, you can try to recover your Microsoft account by using the account recovery options available on the Microsoft website.
