Microsoft Store - "This code has already been redeemed" error message

Your Microsoft Flight Simulator code is a one-time use code. Once a code has been redeemed it is linked to your Microsoft Account forever—which means you do not need to redeem the code again. To reinstall or launch your game, simply sign-in to the Microsoft Store app and Microsoft Flight Simulator with the email address of the Microsoft Account used to purchase the simulator/redeem the code.

If you do not remember the email address used to redeem/purchase the code, visit Gamertag & Microsoft Account FAQ

If the message "This code has already been redeemed" appears, it means that:

• You're not logged in to the Microsoft Store app with the email address used to purchase Microsoft Flight Simulator/redeem the code.

or

• You're trying to redeem the key on the same account again. Go to How to uninstall and reinstall Microsoft Flight Simulator Boxed Edition.
