Activating Office 2024 is quick and works automatically if you’re using a genuine license. After installing Office, open any app like Word or Excel and sign in with the Microsoft account you used when purchasing the product. Office will detect your license and activate immediately. If you have a product key, go to setup.office.com, sign in, enter the 25-character key, and follow the steps to link it to your account. Once the key is redeemed, install Office 2024 and activation will complete on its own when you launch an app and connect to the internet. Always use official Microsoft or authorized reseller licenses for reliable, long-term activation.
