A program that grants points for using Bing search, which users can redeem for gift cards, sweepstakes entries, or charitable donations.
That message usually points to a region/eligibility restriction, rather than whether you are physically “on the go.”
I’d check a few things first:
Make sure the Microsoft account’s country/region matches the region where the Rewards gift card is being offered.
Check whether the specific gift card is available for your Rewards account/market. Some Rewards catalog items are region-specific.
If you’re using a VPN or proxy, disable it and try again.
Sign out/in and try from another browser or an InPrivate window.
If the same message appears consistently, Microsoft Rewards Support would need to check the account-side eligibility.
I wouldn’t keep trying to redeem it repeatedly if the catalog is explicitly saying the item isn’t eligible. The important detail for Support is the exact gift card, account region, and the error message.
If everything matches and other Rewards items work normally, this looks more like an eligibility/catalog issue that Microsoft needs to investigate on their side.
