To verify if the emails you received from "Microsoft" regarding your defender membership are genuine, you should check the sender's email address. Legitimate emails from Microsoft typically come from the following domains:
- microsoft.com
- microsoftsupport.com
- mail.support.microsoft.com
If the email is from a different domain, such as one that looks suspicious or unfamiliar, it is likely a phishing attempt. For example, emails from addresses like ******@outlook.com or ******@microsoft.net are not from Microsoft support.
Additionally, do not click on any links or attachments in the email. Instead, you can visit the official Microsoft website directly to check your account status or any required updates. If you suspect the email is a phishing scam, you can report it to Microsoft and avoid engaging with the email further.
