Outbox not shown anywhere

I can not find the Outbox. I have a large attachment that is too large for Gmail and I keep getting error messages to that effect. I don’t show “Smart folders” only my email accounts and their folders which do not contain an Outbox folder. How do I add the Outbox folder to my accounts? I’m using win 7 and eM Client version 7.1.30794.0

I finally found the Outbox. It was under “Menu” > “Tools” > “Settings” > “General” > tick the “Smart Folder” box apply.
