I bought 365 from Amazon in November. My laptop failed and was cleaned. Now cannot check how to reinstall - MS Dashboard don't show answer. Appreciate any advice on steps to take. Even passkey won't let me in.

    When you first installed and activated Office that licence should have become associated to your Microsoft Account as a digital licence online and it is from there that you can re-install Office without the need for a product key:

    https://account.microsoft.com/services/

    On your account, do you find your Microsoft Office licence/subscription and is there an install button available?

    To reinstall Microsoft 365 after your laptop has been formatted and data lost, follow these steps:

    1. Sign in to your Microsoft Account: Go to the Microsoft 365 sign-in page and log in with the Microsoft account that you used to purchase Microsoft 365.
    2. Access the Microsoft 365 Dashboard: Once signed in, navigate to the Microsoft 365 dashboard. Here, you should see your subscriptions listed.
    3. Install Microsoft 365: Look for an option that says "Install" or "Install apps". Click on it to start the installation process. Follow the prompts to download the installer for Microsoft 365.
    4. Run the Installer: After downloading, open the installer and follow the on-screen instructions to complete the installation.
    5. Activate Microsoft 365: Once installed, open any Microsoft 365 app (like Word or Excel) and sign in with your Microsoft account to activate your subscription.

    If you encounter issues with your passkey or can't access your account, you may need to recover your Microsoft account or contact Microsoft support for assistance.
