Windows 10: Message in Junk Mail supposedly from Microsoft

Received a security alert from Microsoft regarding unusual sign in activity. Since this came over to junk I am not sure it is legit. I did not open. How can I tell if this is real or fake?

Windows Live Mail Junk not junk

I don't see those options on my Hotmail account....on the web <---- I access my email from on the web, not on my desktop. Here is a pic of my Junk mail folder....on the web...






Hotmail.com AND Outlook.com are same mail programs.....on the web....

 

Outlook Junk Mail Filter Stopped Working

I am running Microsoft Office Professional Plus 2016. In the past about 70% of my email message would be sent to the junk mail folder. Now Outlook rarely flags any message as junk. I have set the Junk Email Options to "High" and have run the Office Repair Function. Nothing has helped. Any suggestions will be appreciated.

 

Windows Live Mail Junk not junk


OK.
If I have the junk folder open on the left of the screen with a list of EMails there, and on the right half of the screen there is a screensaver, ngiht sky with a swirl of stars...........must be the default as I have not changed it.
Click on any message and content is now shown on right side of screen.
To the xtreme left of the message list are 4 icons at top, Expand, New Mail, All accounts and all folders.....at the bottom left 4 more icons, Mail, Switch to Calender, Feedback and Settings.
If I right click on any message in the list, I get 4 icons Delete, Set Flag, Mark as read and Move

Am I missing something ?
