Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi, @Lara Elliot
What device and operating system are you using, Windows, Mac, iPhone, iPad, or Android?
What is the exact error message or error code when you try to activate Word?
Also, open Word and check File > Account or the profile icon. Does it show the correct Microsoft account, or is another account listed?
For now, sign out of all accounts in the Office apps, close them completely, restart the device, then sign back in using the account shown under Services & subscriptions here: https://account.microsoft.com/services
