What you're saying, forgive me, doesn't make sense.
What version of Outlook are you using?
In the navigation pane you should see "Inbox", "Sent Items", "Deleted
Items", "Drafts" and a few others plus groups that take you to Calendar,
Contacts, Tasks, etc.
You can't tell much of anything about e-mail accounts from the
Navigation Pane, typically.
Forgive me -- I've never set up multiple e-mail accounts before. I thought I
had to have a folder for each e-mail address. How do I sort it according to
which e-mail account it was sent? Could I do that through e-mail rules?
