My email is [PII removed]@gmail.com

I had bought my lifelong Microsoft plan, for lifelong, when I bought my Macbook Pro in 2020.

However, I recently found out that, I could not edit all my previous saved Microsoft Word documents on "Word", I could not use new documents to type and save new "Word" documents.

I really bought the plan in 2020 for life long use in my Macbook Pro and licence.

However, it is so strange? It recently tells me to purchase the licence and pay, in order to use "Word"?

please help please help

    Hi, @Clarice Wong

    Sorry you're dealing with this, and I get why it feels like a bait-and-switch. Before trying anything else, there's one quick check that will probably explain the whole thing.

    Open Word, click Word in the top menu bar, then About Microsoft Word. Look at what it says near the top: Office 2019, Office 2021, or Microsoft 365.

    If it says Office 2019 (which is what most Macs bought in 2020 came with), unfortunately this isn't an account or activation problem you can fix. Starting July 13, 2026, Office 2019 for Mac went into "reduced functionality mode" because the certificate that verifies its license expired and 2019 can no longer be updated to a version that carries the new one. Word can still open and print your files, but it can't edit, save, or create new ones. Reinstalling, signing out and in, or resetting the license won't bring it back. Your documents are not damaged or lost, they're just read-only in that app now.

    Your options at that point are: use Word for free in the browser at office.com (sign in with your Gmail-based Microsoft account, upload the file, edit, download it back), buy Office Home 2024 as a new one-time purchase, or go with a Microsoft 365 subscription. If you only need Word occasionally, the web version honestly covers most everyday editing.

    If About Word instead says Office 2021, you're in better shape. Make sure your Mac is on macOS 12 Monterey or newer, then in Word go to Help > Check for Updates and install everything. That update carries the renewed certificate and editing should come back. One heads-up: a mid-October build (16.114.x) caused a "license not supported" error for some Office 2021 users, so if the update makes things worse, it is recommended to grab the current 16.115 installer from Microsoft's Office for Mac update history page and run that.

    Let us know what About Word shows and we can take it from there.

    Sign in with the Microsoft account linked to your 2020 one-time Office purchase and reactivate that license; do not buy Microsoft 365 unless the purchase cannot be found on any of your accounts.

    1. Find the account holding the licence

    Your Gmail address can be used as a Microsoft account, but the licence belongs to whichever account was used to redeem or activate Office in 2020.

    1. Open the Microsoft account Services & subscriptions page: https://account.microsoft.com/services
    2. Sign in using the Gmail address you used in 2020.
    3. Look for a product such as Office Home & Student, Office Home & Business, or Office 2019/2021 for Mac.
    4. If it is absent, try any other email address you might have used. Search your email accounts for the original Microsoft order, redemption, or activation confirmation.
    5. If Microsoft sold it directly, also check Payment & billing → Order history, selecting a date range covering 2020.^1^

    The free web version of Word appearing on the account does not prove that the desktop licence is attached. The specific Office product must be listed under the account.^2^

    2. Reconnect Word to that licence

    Once the one-time purchase is visible:

    1. Open Word.
    2. Select Word → About Microsoft Word.
    3. Check the email beside Belongs to.
    4. Select More Info → Refresh License.
    5. When prompted, sign in with the account that displays the one-time Office purchase.
    6. Close and reopen Word, then test editing and saving a new document.^3^

    3. If Word came from the Mac App Store

    Only follow this branch if Word’s App Store page shows that it was installed from there, or if you recently replaced or reinstalled Word through the App Store.

    Mac App Store versions of Word, Excel, and PowerPoint require Microsoft 365 and cannot be activated with a one-time Office licence. For a perpetual licence, install Office directly from Microsoft instead.^4^

    1. Close all Office applications.
    2. Open Finder → Applications.
    3. Control-click Word, Excel, PowerPoint, and Outlook, then select Move to Trash.
    4. Return to https://account.microsoft.com/services and sign in with the licensed account.
    5. Select the installation option beside the listed Office purchase.
    6. Run the downloaded installer, open Word, and activate it with that same account.

    Removing the applications does not delete Word documents stored in Documents, Desktop, OneDrive, or other folders.

    4. If the correct purchase is listed but activation remains locked

    Reset the locally stored Office licences:

    1. Ensure that you know the licensed account’s email address and password.
    2. Download Microsoft’s Office licence removal tool from the official instructions.
    3. Open the downloaded .pkg file and complete the wizard. A Mac administrator password may be required.
    4. Open Word and sign in with the account holding the one-time purchase.
    5. If offered multiple licences, select the one-time Office licence associated with the 2020 purchase.
    6. Restart the Mac after activation.^5^

    This tool removes saved activation data from the Mac; it does not remove the purchase from the Microsoft account.

    About “lifetime” Office

    A one-time purchase is for the Office release purchased, rather than a recurring Microsoft 365 subscription. It does not include upgrades to later major releases.^6^

    If the product is Office 2019 for Mac, support and security updates ended on October 10, 2023, but Microsoft states that the software can still be used.^7^ End of support by itself does not convert that licence into a subscription.

    If no Office purchase appears under any likely account, locate the 2020 receipt or product-key record and contact Microsoft Support for purchase/account assistance. Do not post your full email address, product key, receipt, or other account information publicly.
