Preventing Winmail.dat Files Attached to Email

I have a end user that when sending attachments via Outlook the attachment is converted to a winmail.dat file. The receiving end is not able to open.  Anyone know how to fix this?

TNEF is MAPI based which is what Microsoft uses.  Not all clients are able to read the attachments when composed using RTF so it's advised to use Plain Text / HTML when sending to clients not using Outlook.
