Verify mail address <******@customermail.microsoft.com>

Question

Is this an authentic MS address? Microsoft Rewards******@customermail.microsoft.com It was included in a MS Rewards promotional mail:

Answer 1

Hi, I'm John!

Yes, that domain can be legitimate.

@customermail.microsoft.com is used by Microsoft for some automated emails, including Microsoft Rewards.

But don’t rely on the address alone. Emails can still be spoofed.

Here’s what to check quickly:

1. Did the email ask you to click a link or sign in?
2. When you hover the link, does it go to a real Microsoft site (like microsoft.com, bing.com, or rewards.microsoft.com)?
3. Any urgent or suspicious wording?

Safer option:

• Don’t click links in the email.
• Go directly to the official Rewards site and check there: https://rewards.microsoft.com

Answer 2

The domain customermail.microsoft.com is owned by Microsoft, and it is commonly used for automated or bulk communications such as newsletters, promotions, and services like Microsoft Rewards. An address like ******@customermail.microsoft.com fits the pattern Microsoft uses for outbound messaging, so on its face it can be legitimate.That said, the displayed “from” address alone isn’t enough to guarantee authenticity, because email headers can be spoofed. To be confident, you should check the message’s full headers for authentication results like SPF, DKIM, and DMARC all passing and aligning with microsoft.com. Also look at where any links in the email actually point before clicking them, and confirm they go to official Microsoft domains (like microsoft.com, bing.com, or rewards.microsoft.com).

If those checks look clean and the content matches typical Microsoft Rewards communications, it’s very likely genuine. If anything seems off, it’s safer to ignore the email and access Microsoft Rewards directly through your browser instead of using links in the message.
