my txt is not sending pdf

It happens to all attachments regardless of who I send it to and the format of the file (e.g. PDF, Word, jpg, etc). If I send the same attachment through web mail or from another computer, the attachment remains intact and is received in the email. I've tried turning off my anti-virus program but that's not made any difference, so I'm assuming the issue must be within Outlook itself.
