Individual accounts INBOX

In the left pane, there use to be a COMBINED INBOX for all accounts and then an INBOX for each account under that. Now, all I have is the combined INBOX. How do I get the individual INBOXES at the top under the combined inbox like I had?

Thank you…

You should see a little arrow to the left of the Combined Inbox, pointing right. If you click this, it should expand down to show the individual inboxes. (You can do the same to any of the other summary folders in the top section - the trash, sent items etc.)
