Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Greetings!
This is Tin, I'll do my best to help. Sorry to hear that you're having issue with activating your MS Office Word. To check if the license is associated with your account, please sign in to https://account.microsoft.com/services and sign in your account. If it's not showing there, please check your other accounts that you might use to purchase the license as it should be associated with that account. If you don't mind me asking, did you buy this license or is it preinstalled MS Office?
Will wait for your response.
Thanks,
Tin
