Unusual Account Activity from MS IP Addresses

Yesterday I received an email from your Microsoft Account Team regarding unusual activity.  When I looked into it, it showed an unusual actvity detected for an Automatic POP3 sync from IP 13.101.248.75.  This activity did not have my account alias listed as it usually does, and listed the location as United States.  On the review activity page I said this was not me.  I changed my password, but then saw another unusual account activity from IP 13.101.248.41. This one did have my account alias listed.   I changed my passwords almost 1/2 dozen times yesterday.24hrs after my final password change, I received today another email regarding unusual activity.  It was another unusual activity detected for an Automatic POP3 sync from IP 13.101.248.75. Once again I confirmed this was not me, although this time I did not change my password.  Three hours later, I received yet another notification of unusual activity.  This time it was for IP 13.101.219.207  However, at the same time it had the exact same thing for IP address 13.101.53.212.  While I was not notified of that one, nor asked to confirm if this was me, it does list it as unusual activity. I looked all the IP address up on ARIN WHOIS.  According to them they all belong to Microsoft. I am sending this to all the email addresses on ARIN WHOIS that are listed as a point of contact.  I NEED ANSWERS. This has never happened before yesterday. I am afraid to confirm that these are me because I don't understand why MS IPs would be POP3 syncing to my account. I only have my Gmail account to POP3 sync to this email.  Those IP addresses tend to begin with a 2607 number.  I keep saying this isn't me, but not sure what I should do. Ignore, confirm it's me or continue to say it's not me. I want to know why is a Microsoft IP auto syncing to my email account? So much so that it generates an unusual activity text/email?I NEED some guidance on this.  There is no help article covering this.  And there is no way to contact a live person for help, which is ABSOLUTELY RIDICULOUS!

Finally got to talk to someone at MS- this was their reply:

Thank you for the information. Please be advise that Microsoft is aware of this known issue already. This started to happen even last week and we are already working with this matter. We even have created a ticket number for this issue while it is still happening.

The ticket number for the emerging issue is INC31680156.

So they are on it, but no idea when it will be fixed.

[EDIT] They also confirmed that the account was secure, no need to change passwords, etc

    Thank you Chandy.

    Finally heard back from MS outlook.com support. It's clear that they didn't bother to read any of my follow up replies to their intial response, as they simply sent me a link to explain "what is the recent activity". Beyond frustrated at this kind of response from support.

    The last notification I got of unusual activity was 1:11pm CST yesterday. Protocol: POP3 IP: 13.101.218.73. However, it shows that I had unusual activity from Protocol: POP3IP: 13.101.248.41 at 5:27pm CST, and again around midnight. No text or email notification regarding that IP.

    This seems to be affecting other countries as well. A volunterer moderator posted on this forum https://answers.microsoft.com/en-us/outlook_com/forum/all/outlook-mail-account-unusual-activity/6cfb226f-8cd7-41ae-bd0a-a80d100af543?page=7  that he had been notified by a German blogger that he was experiencing these issues. There are active reddit threads regarding this as well. One of the reddit threads has people from the UK.
