How to Activate Microsoft Office 365 Lifetime

In this step-by-step tutorial, we will guide you through the complete installation and activation process for Microsoft Office 365 using the account details provided in your Keyzens order email. Please ensure you have a stable internet connection before starting, as the installer will download the latest version of Office directly from Microsoft’s servers. Follow the video carefully to complete the setup correctly.

Important Note Before You Begin

Before starting the installation, we strongly recommend uninstalling all existing Microsoft Office applications from your computer. This helps prevent activation conflicts, version mismatches, or sign-in errors during setup.

Your Microsoft Office 365 should now be successfully installed and activated. You can start using Word, Excel, PowerPoint, and other Office applications immediately. If you encounter any issues during installation or sign-in, please double-check that you are using the correct account details and updated password. For further assistance, our Keyzens support team is always ready to help.

macOS Installation

For macOS devices, download Microsoft 365 directly from the Mac App Store. Before signing in to the Office apps for the first time, you must first visit login.microsoftonline.com using a web browser and sign in with the username and temporary password provided in your Keyzens order email. You will be prompted to create a new password during this first login. After successfully updating your password, open the Office apps on your Mac and sign in using the same username and the new password you created to complete activation.
