I am getting a lot of complaints from my freinds and relative that, they are receiving a attachment in my mails called winmail.dat file. As i had never attached any file in the mail. I just send a clear messages to my freinds. I am not aware that how these attachment's are created automatically in my emails. I am using Outlook Express to work with my mails. What is the cause for this and how to get rid of it. Help.
