When is microsoft rewards coming to Greece?

That'd be an inquiry for the Rewards team to answer although I suspect there wouldn't be any public time frame for that.

Hello HeatedDread4,

Greece is not a eligible Rewards region, so you cannot register into the Xbox Live Rewards program.

Hello Chronix GRE,



Your deposit is being prevented due to a mismatch between your British Rewards Account region and your Greek Microsoft Account region. When you register into the Rewards program, we create a Rewards account based on your Microsoft Account region at the time
of registration. Since your Rewards Account is a separate entity from your Microsoft Account, migrating your Microsoft Account region will not also change your Rewards Account region. Therefore, when your Rewards Account attempts a deposit in one regional
currency, it cannot complete when your Microsoft Account is of a differing currency. Note that Greece is not a Rewards region, so this issue can only be fixed by heading over to the Microsoft Commerce page at (https://commerce.microsoft.com)
to update your Microsoft account to match your Xbox Live Rewards location.

First, welcome to the Xbox community. Unfortunately, at the moment, there is no official information about this, however, if there are plans for this usually Microsoft keeps the public informed by the official Xbox website below.

*Thank you in advance for contacting the community, I hope this can help you. Let me know if you have more questions, please.

Hello again!

It seems that it can be done through the Ireland Microsoft store! Delivering to Greece and paying from Greece is possible.
