Hello BowlerFan,

If Xbox Live Rewards is unable to deposit into your account for some reason, as long as you have not opted out to make the transition to Microsoft Rewards, any undeposited Xbox Live Rewards Credits and unredeemed MyVIP Gems will be automatically converted
to Microsoft Rewards points and be added to your Microsoft Rewards account to redeem for whatever you choose from the Microsoft Rewards catalog.

transition to Microsoft Rewards.

Since this issue only affects your Xbox Live Rewards account, and Microsoft Rewards does not do deposits in the same way, it will not affect your Microsoft Rewards account.
