I am running Win 7 with WLM 2012. Any email sent without an attachment is saved in Sent folder and appears in the sent listing. Any email with any attachment whether a jpg or pdf does not appear in Sent folder. The email files .eml are stored in User/App Data/Local/Microsoft/WLM in the folders for the identity. When you look in the sent folder you can see the email with the attachment as it is larger and also by the time sent. Double clicking on this brings up select a program (even though WLM is set as default) and selecting WLM only opens the program not the individual sent email. I can't get my head round this one so any help appreciated. Apologies if I have missed a previous answer.
