Live.com login activity and a warning "Unusual activity detected"

Anonymous

I could not find a more direct forum than Outlook to ask this question, if it is not the right forum my apologies.

I received an e-mail alert that indicated unusual activity detected on my live.com account. When I checked the recent activity, I found two IP numbers. One matched my external IP and the other did not. I changed my password right away and checked the activity again. To my surprise, the other IP and its variants were appearing along with my external IP number at the same intervals.

I tried to find the IP number roots and ironically, it pointed at Microsoft. I am really confused! Can someone explain the source of this IP and whether I need to do anything to stop it from occurring.? I use Edge browser and I log in with my account. When it syncs, does it use a separate IP from my IP number?

Thank you,

Cemal

Note: I am not using the Outlook mail client. I check my mail using two different mail clients on two different computers at the same location that share the same external IP number. On occasion, I check my live.com e-mail online using a Web browser.

    I was told that they are still investigating the root cause. So we all need to wait patiently. I'll update here once I get something new.

    I have changed my password twice and have been checking the activity log. In the last two days, I have not seen any unusual login from 13.101.xxx.xxx . That is good news to me. I would like to be informed as to the cause of the problem when the team finds the answer.

    Before this issue gets fixed by Microsoft tech team, here are the things you can do:

    1. Change your Microsoft account password
    2. Add security info to your Microsoft account
    3. Sign out your Microsoft account from all the apps and all the devices
    4. Check if you were using VPN

    One thing I noticed was when I use my regular mail client, I get the unusual activity report. I closed and did not use the mail client for almost a day, and the unusual activity from the connection reports. When I start using the mail client unusual activity starts showing up. I started a ticket with the mail client software company as well.
