I have been trying for over a week to correct an error message on Office Home & Student for Mac. I deleted Office 2008 and Office 2021 to reinstall. I do not have my product key, only my device ID, Session ID and License ID. Where can I find my product code after I was instructed to delete and reinstall Office 2021? Thank you.

    Hello, thank you for reaching out to Microsoft Q&A.

    May I please know how and where you purchased your Office 2021 license? Did you buy it through a third-party retailer or directly from the Microsoft Store?

    Also, could you please check if your Office 2021 license is registered in your Microsoft account? You can verify this by signing in to the Services & Subscriptions page of your Microsoft account.

    See the "Products you've purchased" section.
