Outlook Login Session Traceable?

[SOHO2012]

Hello, I am concerned that someone has my email password and has been logging into my outlook 365 email account and simply viewing my sent and received messages. Is there a way to track the login sessions to a time, IP address, or physical location? Thanks for your help.

I haven't had any luck finding that option. (yahoo offers it) I would suggest going through and changing your password, all of your security settings, and security questions and answers if you think someone is gaining access to your account.
