how do I get product key for office 365

If You Purchased Office 365

• Microsoft Account: Office 365 does not typically require a product key; instead, it is linked to your Microsoft account. You can sign in at https://account.microsoft.com/services to manage your subscription.

• Email Confirmation: If you purchased Office 365 online, check your email for an order confirmation from Microsoft.

• Retail Boxed Copy: If you bought a physical copy, check the packaging or card inside for a 25-character product key.

If You Have a Preinstalled Version (OEM License)

• Some new laptops come with Office preinstalled. You can check your Microsoft account to see if the license is linked or look for a key on a sticker or card provided by the manufacturer.

Through an Organisation or Business Subscription

• If you got Office 365 through work or school, you don’t need a product key. Instead, sign in with your organisation’s credentials at https://portal.office.com.

Microsoft 365 Business or Enterprise Plans

• If your company provides a license, check with your IT administrator. They may assign you a license that does not require a product key.

If You Need to Buy a License

• Visit https://www.microsoft.com/en-gb/microsoft-365/get-started-with-office-2021 to purchase a subscription.

If you are paying for a subscription, you don't need a product key, and in fact you can't (re-)use any product keys that you have used in the past. You install and activate Office using your account at https://account.microsoft.com/services.

If you are saying that you do not have an Office product, the cheapest option is to get a one-time payment license such as Microsoft Office Home 2024. It is for one user and one computer (PC or Mac). See https://www.microsoft.com/en-us/microsoft-365/p/office-home-2024/cfq7ttc0pqvj.
