Is the Microsoft account security alert legit?

I've just received two emails in a row stating that "We detected something unusual about a recent sign-in for the Microsoft account" and "someone else might have accessed the Microsoft account..." (see image attached). Seems a little "phishy" to me considering it's a gmail account. Last time I checked, Gmail was owned by Google, not Microsoft. But what's weird is when clicking on the recover account button it appears to lead to the real Microsoft website. Can someone please confirm if this is a scam?
