In Office 2013 there are functions for sending a document or workbook as an e-mail directly from word or excel. The function is located at File > Share > Send as e-mail (or might be Send with e-mail, my translation may be faulty). An new e-mail in outlook opens with the file attached and the user types som random text as message. The e-mail is properly sent but when afterwards inspecting the sent items the random text in the message itself is gone. The file is properly attached so it only effects the text in itself.
Thanks in advance!
