Sometimes Outlook might have problems sending a message. There may be various causes- corrupted PST, AV scanner etc. The message, instead of going to the Sent Items folder, sits in the Outbox indefinitely.

To remove it you can use a free tool called MFCMAPI
1. Download MFCMAPI from this page: https://mfcmapi.codeplex.com/releases/view/617103 and launch it.
