I bought an Office key, entered it at setup.office.com but it says used. What can I do? 



If in case, this isn't your first time entering the key, it may be best to check if it has already been added to your Microsoft account. 

The solution below ONLY applies to software that are binding to Microsoft account. Here's the list of binding Office software: Microsoft Office Professional Plus 2021, Office Home & Business 2016 for Mac, Office 2019 Home and Business for Mac, Office 2021 Home and Business for Mac, Office Home and Student 2019, and OFFICE HOME & STUDENT 2016 PC



To check, please follow the instructions below: 


1. Go to your Microsoft account dashboard and if you're not already signed in, select Sign in. Make sure to sign in with the Microsoft account you associated with this version of Office.


2. From the top of the page, select Services and subscriptions and on that page, check if the Office you bought is there, then select Install next to it.



If you can't find your Office under Services & Subscriptions, you can also check it in your Order History. Refine your search by selecting All under Show, and All available under Ordered within.




To install Office in a different language, or to install the 64-bit version, select the link Other options. Choose the language and bit version you want, and then select Install.


For Office product keys that are NOT mentioned above, please make sure that you have followed the instruction sent along with your key in My Orders.
