security messages from someone else’s account

Hello,

I have just received three messages from Microsoft Account Team for an account with a very similar e-mail address to my own. The headings for these messages are: Microsoft account security code, Microsoft account security info confirmation and Microsoft account security confirmation. I had initially not noticed the discrepancy in the address and followed the links to cancel and change my password as I thought my account had been hacked.

I was unsure if this was a Microsoft error or if the other user had entered an incorrect address to receive security info. I am also unsure if by cancelling these actions I have affected the other account . Should I take any further action or is this likely a one off?

Thanks in advance for your response.
