Where are the 71 messages associated with the envelope icon on my lock screen?

[Windows Central Question]

In the lower left corner of my Windows 10 lock screen is an envelope icon with the number 71 next to it. Those messages are not in my email in-box. Can there be email accounts associated with my Microsoft Live account that I am not aware of? How do I find out?

Are they in another folder rather than the Inbox?
