Don't see any email in inbox

For a first time I tried to setup email via IMAP.

In Email module I don’t see any emails in Inbox, but when I setup email account and tested it, I was reseiveing: “Connection completed successfully.”

What can be a problem?

Try disabling AOP in system settings. If that helps your problem may relate to following bugs:
