I signed up for Microsoft 365 personal - 1 month free trial - but my operating system: Monterey 12.7.6 will not support this. Can you cancel my order please. I would have to get a new computer.

I'm not a child...

The bot got the name of the article right, but forgot to include a reference link. Here's how to download, install and activate Office on your older Mac: Most Recent Office You Can Run - Best Practices

    Hello, I'm Quinn and here to help!

    Since you signed up for Microsoft 365 Personal (1-month free trial), here’s how to cancel the Free Trial

    1. Go to: https://account.microsoft.com/services
    2. Sign in with the account you used to subscribe.
    3. Find Microsoft 365 Personal.
    4. Click Manage.
    5. Select Cancel subscription (or Turn off recurring billing).
    6. Follow the prompts to confirm cancellation.

    As long as you cancel before the trial ends, you won’t be charged.

    Monterey 12.7.6 can still run supported Microsoft 365/Office builds, so a new computer is not required just to use Word, Excel, or Outlook.

    For macOS Monterey, the most recent supported Microsoft 365/Office version is 16.89 (dated September 10, 2024). With an active Microsoft 365 Personal subscription, that version can be downloaded, installed, and activated on the existing Mac.

    To proceed, install the latest Office version that supports Monterey (for example, following the guidance in “Most Recent Office You Can Run – Best Practices” referenced in the Q&A), then sign in with the Microsoft account used for the Microsoft 365 Personal subscription to activate it.

    Cancellation of the subscription itself cannot be performed here. To cancel a Microsoft 365 trial or subscription, use the standard subscription management and cancellation options in the Microsoft account or the store where the subscription was purchased.
