What is the separation of incoming emails in MS Outlook?

Some time ago, a year or two, your outlook email Inbox (spam does not count) began to podrazdelyaetsya two subfolders: sorted and other. By what logic is this happening I don't understand. Basic confirmation of registration from one site falls into one, another to another. I would like this very logigu to understand. Can someone explain?

"Other" includes distribution, automatic notifications (interestingly, the letters for password recovery don't go to that often).
In the "Sorted" get letters from people.
Well, you can tell what letters where to put. Here I received a letter mailing Tinkoff-log and fell into the "Other". You can ask Outlook for the future to put these letters in the "Sorted":

And, you can disable sorting — View → Show sorted:
