Frequently Asked Questions
Why does my Office 2024 key say it has already been used?
Microsoft Office product keys are single-use codes that permanently link the software license to your Microsoft account. Once redeemed the first time, you cannot use the 25-character key again for reinstallation.
How do I find which Microsoft account is linked to my Office key?
You can check the 'Services & subscriptions' page of any Microsoft accounts you own. The account that lists Office Home 2024 under the purchased products is the one linked to your key.
Can I transfer my Office Home 2024 license to a new computer?
Yes, but you must first uninstall Office from the original computer. Then, sign in to your Microsoft account on the new computer and download the installer directly from your services page.
What if I lost the Microsoft account used to redeem my key?
If you no longer have access to the account, you will need to contact Microsoft Support and provide your original proof of purchase (such as a retail receipt or digital invoice) to see if they can recover or transfer the license.
