You can try several things:

1. Disable and re-enable Cached Mode. In Outlook go to File -> Account settings -> Change account, and uncheck "Use Cached Exchange Mode". Close Outlook, then open it again and check the option "Use Cached Exchange Mode" again.

2. Go to File -> Options -> Mail -> Save messages, and verify "Save copies of messages in the Sent items Folder" is checked, and the option "When replying to a message..." is not checked

No it is not a shared mailbox it is my own e-mail.

Have you checked for the corresponding option in Outlook (and/or OWA)?
