Windows 10: Emails from Microsoft Account Team regarding "Microsoft account unusual signin activity"

For some time I have received emails from Microsoft Account Team stating "Microsoft account unusual signin activity". I went to my recent signin activity data and found my own signin activity plus seven other signin attempts all unsuccessful in the last 2 weeks. They were from 7 different cities and IRL's, all not mine. This is very concerning. How can I prevent the attempts? Would these IRL's be of any use to your security group? Thanks for your assistance.

Microsoft account unusual sign-in activity email.

Hi Billyv1988, I am Paulo and I'd like to help.

You'll know it's legitimate if it's from the Microsoft account team at *** Email address is removed for privacy ***

If there wasn't anything unusual, the email message is a phishing scam

 

Microsoft account unusual sign-in activity

Thank you for the reply. I have answered your questions in bold.

But I still fail to see why any of the questions/measures apply to my situation when Microsoft's "Review recent activity" log shows no "unusual sign-in activity" whatsoever. There are approximately 20 sessions showing on my activity log currently, and everyone
single one of them shows them to be: my computer, my IP address, my location, my operating system, my browser; all at times of the day when I was on my computer...

So unless Microsoft's "Review recent activity" page is inaccurate, where on earth is the "unusual sign-in activity" and why am I getting daily emails alerting me to something, that according to Microsoft's "recent activity" log, does not exist?

Thanks for your continued help/efforts,

SR

03/03/17: Update: and, FTR, I got the email again last night, 8 days in a row now. And once again, there is no "unusual sign-in activity" showing in my "recent activity" whatsoever.
