Question about Outlook Express

Dear support,

I receive the email subjected : Microsoft account security code, it says‏

"Hi,

Thanks for helping us verify your Microsoft account (*** Email address is removed for privacy ***)!

Here is your code: *****

If you didn't request this code, we recommend that you go to https://account.live.com and change your password.

Thanks,
The Microsoft account team"

But it is not for my email address. My email address is *** Email address is removed for privacy ***.  I received it 5 times today. I'd ask what is happened? And How can I do? Ignor it?

Thank you for your support.

Regards,

Kukkui
