Hello CECILPHILIP, thank you for reaching out to the Microsoft Community. I am here to help and provide assistance with any questions or concerns you may have.
Fraudulent email messages have been received warning about potential account access attempts, fake verifications, or even threats of account closure.
As you mentioned, these emails are a typical example of phishing attempts, a fraudulent practice aiming to deceive and obtain personal information. Never provide any personal information via email, Microsoft will never ask you for this.
Legitimate emails from Microsoft will come from this address: ******@accountprotection.microsoft.com
https://support.microsoft.com/en-us/account-bil...
If an email does not come from this trusted source, I recommend right-clicking on the email and selecting "Report" and then "Report phishing" to help Microsoft improve its algorithm and prevent future phishing cases.
Additionally, you could create a mail rule to directly send such messages to the spam folder.
Let me know if you have any other questions or if there's anything else I can do to assist you.
