I have confirmed I am logged into the correct account. The purchase of the product shows on my Subscriptions page, but I cannot get it to activate. It is giving me a No license found error repeatedly. Please advise.

    Office Home & Business 2021 is a one-time license and must use Office apps downloaded directly from Microsoft—not the Mac App Store—so first replace any App Store copy with Microsoft’s Office 2021 installer.

    1. Reinstall the correct Office 2021 build

    Apps obtained from the Mac App Store require a Microsoft 365 subscription and cannot activate with a perpetual Office license. Microsoft’s direct installer includes the licensing helper required by Office Home & Business 2021.^1^

    1. Close Word, Excel, PowerPoint, and Outlook.
    2. Open Finder > Applications.
    3. Select the Office apps, Control-click them, and choose Move to Bin.
    4. Download the Office 2021 for Mac Installer directly from Microsoft.
    5. Open the downloaded .pkg file and complete installation.
    6. Open Word from Launchpad, select Get Started, and sign in with the account already showing the Office 2021 purchase.
    7. Restart the Mac after activation.

    2. If the Microsoft-installed copy still reports “No license found”

    Clear the locally cached Office licenses. This removes activation data from the Mac, not the purchase from the Microsoft account.^2^

    1. Close every Office application.
    2. Download and run Microsoft’s license removal tool.
    3. Open the downloaded .pkg, select Continue, and complete the wizard. A Mac administrator password may be required.
    4. Reinstall Office from the direct Microsoft installer above if necessary.
    5. Open Word and sign in again to activate Office 2021.
    6. Restart the Mac.

    Alternatively, Microsoft’s activation procedure says to open Spotlight > Keychain Access, search for Office, delete the Office data-license entry, and then run the Microsoft 365 Activation troubleshooter through Get Help.^3^

    3. Check the licensing-helper folder

    For a confirmed one-time purchase that still cannot activate:

    1. Open Finder > Go > Computer.
    2. Navigate to Macintosh HD > Library.
    3. Inspect PrivilegedHelperTools.
    4. If it has a red stop icon, open Terminal and run:
    cd /Library
sudo -s
chmod 755 ./PrivilegedHelperTools
exit

    Enter the Mac administrator password when requested; Terminal will not display password characters. Quit and reopen Office, then activate again.^3^

    If the folder is accessible but empty, uninstall and reinstall Office from Microsoft, then confirm it contains com.microsoft.office.licensingV2.helper. That helper provides device-wide activation for perpetual licenses such as Office Home & Business 2021.^4^

    If Word or Excel is version 16.114.1

    Check Word > About Word or Excel > About Excel. If the exact error says that the Office 2021 license is unsupported with application version 16.114.1, a closely matched Microsoft Q&A case recommends completely uninstalling Office, installing version 16.114, and temporarily turning off automatic updates.^5^

    This is a community-reported workaround, not a formal Microsoft Support resolution. Staying on an older build or disabling automatic updates can delay security fixes. Check manually for a corrected build and re-enable Help > Check for Updates > Automatically keep Microsoft apps up to date as soon as Microsoft publishes one.

    If activation still fails

    Open the macOS Get Help app and contact Microsoft Support. Provide:

    • macOS version
    • Office application version and build
    • Exact activation error
    • Screenshot showing Office 2021 under Services & subscriptions
    • Confirmation that the Microsoft installer, license-removal tool, and helper-folder checks were completed

    Microsoft Support must investigate or correct any account-side entitlement that remains unrecognized.

    I know how confusing this is, Saraswati Khalsa.

    And you don't seem to be the only one. There have been other reports from community members over disappearing license for their Office 2021 edition. I can't guarantee that you're in the same situation, but it's worth trying what worked for them. Please follow the steps below carefully:

    1. Remove the current Office license from your Mac with the Removal tool
    2. Uninstall it using this guide: Uninstall Office for Mac | Microsoft Support
    3. Download and install an older version of Office (113.x is recommended)
    4. Turn off automatic-update so Office doesn't go back to newer edition.

    Although Office 2021 already reached end of support, it would still work as long as your license is genuine. I hope the suggestions above help you get your Office apps back to working.

    I have tried this and still no luck. Plus I am getting a crazy run around with my login attempts. It keeps sending activation codes to an email that is no longer associated with the account. I had a separate Microsoft accoutn at that email, so I feel like somehow it is getting confused. I tried to delete that account but it won't delete till the end of hte year so it keeps doing that.

    Hi Saraswati Khalsa, the behaviors you described seem different compared to the licensing issue other members have been reporting. That might be unrelated so we will just go through each of them. First, just to make sure I understand the account situation correctly: when you mention the old email address, do you mean it used to be an alias and you removed it, making it a separate Microsoft account? Or it was a verification method in Security, and you're sure it was removed?

    User's image

    If it's the latter case, do you have another replacement for it? Or you currently don't have any verification method? You may temporarily add Authenticator app or turn off two-step verification (not recommended since it poses security risks) to test.

    Also, when Microsoft sends the code to that old email address, at what point does this happen: when signing in at https://account.microsoft.com, or only when activating Office on your Mac?

    Secondly, I need to note is that the information in my answer is no longer the latest. Like what Stefan said above, the newer version (16.114.3) has resolved the licensing issue. You can download that version now (or directly from your Subscription page) to see if it's working:

    • Remove your Office apps from Finder > Applications to Trash.
    • Then go to Subscriptions > click the Install Office button.
    • Next, open Finder > Go > Computer > Macintosh HD > Library
    • Look for PrivilegedHelperTools and see if it's marked "no access”
    • If yes, and you're comfortable with using command tool:
      • Open Applications > Utilities > Terminal
      • Run cd /Library, then run sudo chmod 755 ./PrivilegedHelperTools
    • Quit Office completely / restart your Mac > reopen Word.

    If none of that changes the message, the remaining likely cause is that the purchase is not being seen as a Mac-eligible Office 2021 license on Microsoft’s side. Since Microsoft Q&A is just a community forum with no access to users' data to verify your license record, you would need to reach out:

    1. Go to Contact - Microsoft Support  > sign in with your account.
    2. Search Contact > Get Help > scroll down and click Ask our Support Assistant
    3. Specifically state in the chat that you need an agent to review > click Contact Support
    4. Choose Microsoft 365 and Office > Technical support (if available) > Confirm.  
    5. You can choose to chat with a support agent on your web browser.

    Note: The support contact team only works at certain times, so if the last window shows that it's unavailable, try opening it again the next day. If you prefer phone support, you can leave a phone number. This way, they can call you and help you. If you don't see chat option, choose another category and ask to escalate.
