It sounds like you are not using IMAP everywhere, and also you may have some other settings, such as "leave messages on server," not setup correctly. There are a few reasons for this. I am not really sure what you mean by "look at my emails" Do you mean sync, or something else?
What do you mean by OUTLOOK? The Office email client (program) called Outlook, or the website called outlook.com? Do the emails never appear, or only some appear? Are they emails you MAKE, or ones you have received?
