When the user tries to create a new email and send it to an external account, then the message remains in the outbox for a limited time before processing completely. Then, it is saved in the Sent folder. If the email remains in the outbox, then it means that your email is not sending email and you should check the outgoing server settings.

If the outlook is not reaching to trash folder or the trash folder is not emptying older messages, then you should troubleshoot such a problem.
