Issue: How to block "Microsoft account unusual sign-in activity” phising scam?

Hi guys. I’m a bit concerned if I have recently received a genuine Microsoft alert on my Outlook account or not. The message says “Unusual sign-in Activity.” Although I see Microsoft account team as a sender, the generated URL address seems suspicious. Besides, the location of the sender is Namibia, which also seems questionable for me. Finally, it’s stated that to save my personal information, my Outlook account will be temporarily blocked, so I should not be able to send or receive emails, BUT I do send emails and receive them. I tried that and received a confirmation from my colleagues that they have just received an email from my account. Could you please help me?

Solved Answer

“Microsoft account unusual sign-in activity” is an email letter which informs about a suspicious sing-in to the Outlook account. In most cases, such emails are legitimate and useful to protect you from hackers. However, cybercriminals invented a phishing technique to trick novice users into giving their credentials — they sent fake letter that look extremely similar to the legitimate ones[1].

“Microsoft account unusual sign-in activity” scam relies on the credulous people who do not pay attention to details. Users should always double check the email address before agreeing to do what is asked or clicking on any contents attached to the letter. Criminals use addresses that are similar but slightly different from the legitimate ones.

Furthermore, you can always contact Microsoft Support directly on their official website, if you wonder whether “Microsoft account unusual sign-in activity” alert is safe or legitimate. Additionally, Outlook often marks safe email addresses with the green shield icon. So, if you cannot see one, do NOT open the email.

The scam message says:
