Windows 10: Definition of "Unusual Activity Detected"

Hello, I recently received an email notification that "Unusual sign-in activity was detected." I reviewed the Recent activity page and under the column labeled "Session Type"> "Sesson activity" it was listed with "Unusual activity detected"Does this mean that they were successful in signing into my account or were they blocked by a security code or question?I know there is another question posted with this same subject title, however, they did not get a helpful answer, so I am reposting.Thanks for the assistance!

Definition of "Unusual Activity Detected"

To start off, this isn't about a phishing scam

Within my actual Microsoft Account page under Recent Activity, it states that yesterday there was "Unusual Activity Detected" from China...

Obviously I don't live in China so i've changed all my passwords as best as i can.

My question is, does this mean that they have accessed my account or does it mean they merely attempted and failed ?

Thank you very much

 

unusual activity from the same IP

Earlier today I received a mail that there was unusual activity on my microsoft account. I logged and checked the activity page. It should the unusual activity login as well as the current details of the login I just did to check this activity. Both had
the same IP. I double checked on another site and my IP was indeed that same IP.

On the unusual activity session the following is listed

Device/platform : Windows

Browser/app : Unknown

Session activity : Unusual activity detected

To my knowledge the only app that I am sign into on my account is the MS Feedback hub. Could it be this?

Should I be worried about malware infecting my laptop and that is the cause?
