Outlook 2010 - Attachments are not placed in the body of the text

I have been using Outlook 2010 for some time now and the attachments have had their own line adjacent to the subject line. For some reason this line has disappeared and the attachments are not placed in the body of the text, can some help please?

It might be that you could have changed the email format to Rich Text either by mistake or un-intentionally. So to revert it back you will have to change it to Plain text or HTML. For doing the same, you have to go to Tools >> Options >> Mail Format. Here, just changed to the desired format and everything will be sorted out.
