In my company we have this issue right now and I beg to differ on some of the responses. We have an exchange server inhouse and a mail server hosted on the outside via POP accounts. When a user in my facility sends an email through the POP account and back in house we recieve winmail.dat. If we send through our exchange, we will not recieve the winmail attachment. If we send an email to and outside address they will not recieve winmail either. Is is only recieved when someone sends an attachment or HTML formatted email from their outlook through the pop account and back inside to our accounts. The POP mail does not touch our exisiting inhouse exchange. The outside email hosting software in Modus mail. We are all using Outlook 2003 in house and still recieving our emails stripped with the winmail.dat attachement. Most of us are using HTML format for emails. I have read that we can change to plain text, but no one wants to do that. It makes the emails so unpersonable.
