Office Home & Business 2021 for Mac is listed as a purchased product in my account but I can not view the license information. I had a hard drive failure and need to reinstall the license file. How can I view the license number so I can use Office again? I am looking for the perpetual license file, NOT the 365 license.

    Hi, @Brian Coleman

    Your perpetual Office Home & Business 2021 for Mac license is activated by signing in with the Microsoft account linked to it. You normally do not need the original product key or a separate license file to reactivate it.

    Are you able to see your Microsoft Office Home & Business 2021 under the Services & subscriptions page here: https://account.microsoft.com/services (make sure you’re signed in with the same Microsoft account you used to activate Office)?

    If you can see it there, please follow these steps below.

    If you haven't already, I’d suggest is to uninstall any existing Office apps on your Mac to avoid conflict:

    Then, to reinstall Microsoft Office:

    • Go to https://account.microsoft.com/services again.
    • Sign in using the same Microsoft account linked to your license.
    • Find your Microsoft Office Home & Business 2021 and click the "Install".
    • That will download the installer for the Office apps, just run it and follow the steps.

    If anything’s unclear or the "Install" option still doesn’t show, feel free to let me know. I’ll be happy to walk you through it!

    Thanks!

    Outlook is asking for the license file. How can I view the license file I've already purchased?

    The license number cannot be viewed in Office or online.

    For Office 2021 for Mac, the Microsoft account associated with the purchase replaces the product key for reinstall and activation. To reinstall after a drive failure:

    1. Sign in to the Microsoft account that was used to buy and redeem Office.
    2. Go to the Microsoft account, Services & subscriptions page.
    3. Reinstall Office from there.
    4. Open an Office app and sign in with that same account to activate.

    If Office is already installed but activation is stuck on the wrong license, check which license the app is using:

    1. Open Word or another Office app.
    2. Go to the Word menu and select About Word.
    3. The dialog shows the version number and license type.

    If old or incorrect license data is causing the problem, the Mac license removal tool can remove all Microsoft 365 for Mac licenses from the Mac, after which Office can be activated again by signing in with the correct account. Important: have the correct account name and password ready before using it.

    If the apps were installed from the Mac App Store, a one-time Office 2021 license is not compatible with those apps. In that case, remove the App Store apps and reinstall the Office apps downloaded directly from Microsoft.
