The Attached4Sure plug-in is an addition to Microsoft Outlook  to remind the user that he has probably forgotten to attach a file to his message. The plug-in reads the message for keywords such as file, attachment, attached, etc.

Attached4Sure will warn you if you have used one of these keywords, and when there is no file attached to your message. It will ask you if you want to send the message anyway, or return to the message to change it.

Take Attached4Sure for a try to see what it's really capable of!
