I purchased a personal Office license, but I can't use it in the program.

I purchased an Office 365 license, but when I open Excel (for example), the menus are disabled. When I go to File > Account and try to enter the email address associated with the license, Office rejects it, stating that it only accepts commercial licenses—even though I purchased a personal, non-commercial license.

    This usually means the desktop app is signed in with the wrong account type or the installed Office copy is conflicting with another Office installation.

    Try this in order:

    1. Sign in with the account that owns the license
      • In the Office app, use the account that was used to buy or redeem the product.
      • If Office says it only accepts a commercial account, verify that the personal Microsoft account actually has the Office product associated with it.
      • Check Services & subscriptions at https://account.microsoft.com/services. The Office product or Microsoft 365 subscription should be listed there. If it is not listed, that account is not the one associated with the license.
    2. Check whether the product was redeemed under a different account
      • If the product was bought from a retail or online store, the product key must be redeemed to a Microsoft account before the apps can activate.
      • If the purchase was made in the Microsoft Store while signed in, that signed-in account is the one associated with Office.
    3. Check for multiple Office installations
      • Multiple installed copies can cause activation conflicts.
      • In Windows 11 or Windows 10, open Control Panel > Programs > Programs and Features.
      • Search for office.
      • If more than one version appears, uninstall the version that is not being used.
      • Restart the PC, then open an Office app and sign in again.
    4. Confirm the app is using the correct license
      • In any Office app, go to File > Account.
      • Under Product Information, check the currently licensed product name.
    5. If the app still shows disabled menus or Unlicensed Product
      • Follow the activation troubleshooting flow for Unlicensed Product:
        • sign in with the correct account
        • check for multiple copies of Office
        • check subscription status
        • continue with activation troubleshooting if needed

    If Office was installed by someone else and their account became associated with the product instead of the purchaser’s account, support is required and proof of purchase should be available.
