Cannot Redeem Gift card on Microsoft Rewards! Please help!

Xbox Rewards credits cannot be redeemed towards a Microsoft store gift card. You may be referring the Microsoft Rewards program which can be redeemed towards gift cards. You would need to contact their customer support via their redemption page.

Once you redeem a gift card from Microsoft Rewards, you cannot turn it back into Rewards points.

You cannot buy Google Play gift cards with Microsoft Rewards Points as they aren't available on Microsoft Rewards or Microsoft gift cards. If you happen to have a redeemed Amazon gift card tied to your Amazon account, you may be able to just search Google
Play gift cards on Amazon and purchase it with your available Amazon credit. Using the Redeem tab on Microsoft Rewards, going to shop, and then selecting the Amazon gift card (if you have enough points) may be able to get you a Google Play gift card you are
looking for on Amazon. Please understand that may work, it is not guaranteed to work.

As another user had pointed out, you could also try and redeem your rewards points for a Walmart or Target eCard (online gift card similar to Amazon) and buy a Google Play gift card through their websites or online or in store. Those are also not guaranteed
to work but may work.

Google Play gift cards aren't currently an available reward option but there are plenty others.

For help with the Microsoft Rewards program, you would need to contact their customer support via their redemption page. Rewards points can only be used to redeem gift cards through the Rewards program, not to be used to make purchases on Live. You would
need to save up enough to redeem an Xbox gift card and then use the money from that gift card.

Please don't forget that these people may also be redeeming Microsoft Rewards point for a $10 gift card.
