Managing personal Outlook.com account settings, security, and privacy
The email address ******@customersfeedback.microsoft.com is a legitimate Microsoft-owned email address. The domain customersfeedback.microsoft.com is a subdomain of microsoft.com, which means it belongs to Microsoft. Microsoft commonly uses this address to send customer satisfaction surveys, feedback requests after support interactions, product experience surveys, and similar communications.
However, you should not rely on the sender address alone. Phishing emails can sometimes display a legitimate-looking sender name or use techniques that make an email appear trustworthy. Before interacting with the message, verify that the actual sender address is exactly ******@customersfeedback.microsoft.com and that any links point to microsoft.com or other official Microsoft domains when you hover over them.
If the email asks only for feedback about a recent Microsoft support case or product experience and does not request passwords, verification codes, payment information, or other sensitive personal data, it is likely legitimate. Microsoft will not ask you to provide your account password or multifactor authentication codes through a feedback survey.
If you are still uncertain, do not click any links in the email. Instead, sign in directly to your Microsoft account or revisit the Microsoft support case through the official Microsoft website to determine whether the survey corresponds to a recent interaction. You can also inspect the email headers if you want additional confirmation that it originated from Microsoft's mail servers.
