You can activate MS Word 365 without a product key if you have a valid Office 365 subscription or help at 1-866-719-1004. Simply download and install the Office suite, then open Word or any other Office app. When prompted, sign in with your Microsoft account credentials linked to your subscription or help at 1-866-719-1004. The software will activate automatically, and no product key will be required. If you purchased Office 365 through your account, Microsoft automatically ties your license to that account or help at 1-866-719-1004, making manual activation with a key unnecessary.
