Windows 10: Unusual sign-in activity for an account I did not make using the same email as my account

Today I received an email from *** Email address is removed for privacy *** about "Unusual sign-in activity" and promptly logged into my account to check, but could not find any sign of my account having been accessed, as the information on the sign-in within the email including the time given were not present in the Recent Sign-in Activity section of my account. I then checked the email again and saw that the name of the account which is always censored is not the right length and contains letters that are not in my account name or associated email.After combing through my ema

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.

 

Microsoft account unusual sign-in activity

Since you have checked your recent activity and confirmed that there were no unusual activities made, please provide us the following information:

• Do you have a new phone from a different provider, or any new apps were installed that might try to sign in using your account?

• Some apps that sign in on your behalf including email apps and social media apps tied to a Microsoft account.
• Apps that sign in on your behalf will need to ask for permissions to do so when they are installed, and will prompt you for your Microsoft account and password.

• Do you remember having to enter your password when you set up any Windows Phone or Windows apps?

If you can't think of any reason why a sign in would occur
from a different location, we strongly suggest that you reset your password and check for unusual activity on any other accounts that you might have.

If you suspect that your account was compromised, you can do the following:

• If apps, services, or subscriptions were purchased with this account:

• Sign-in to account.microsoft.com
• Click Review your purchases and make sure there were no new transactions that you didn't make or expect.
• Click Billing info and make sure your billing info wasn't changed.

• If you're using OneDrive to store and share files, photos, or other data:

• Sign-in to OneDrive.live.com
• Click Shared on the side menu
• Review the folders and files that are being shared to make sure files are not being shared with people you don't know or that any shares you made weren't deleted.

• If you're using an Outlook or Hotmail email account:

• Sign-in to outlook.com
• Click the gear-shaped Settings icon, then click Options.
• Check the following settings and restore any that might have been lost or changed:
• Check the deleted mail folder and Contacts lists to make sure unusual messages or contacts weren't added, sent, or deleted.

Please post back with the result for further assistance.
