Frequently Asked Questions

Why does my Microsoft 365 Military Edition code say it has already been redeemed?

This error occurs if the code was previously activated on a different Microsoft account, or if there was a glitch during activation. Check any other email addresses you own, or contact Microsoft Support with your receipt.

Can I use the Military Appreciation Edition outside the United States?

Military Appreciation Edition codes are often region-locked. If you purchased it at an overseas base exchange, it may still be tied to the US region, requiring your Microsoft account region to match.

What should I do if the physical code is scratched off or unreadable?

Do not guess the remaining characters. Take the card and your store receipt back to the military exchange customer service desk, or contact Microsoft Support directly for assistance in recovering the code.
