What is the Winmail.dat file
On occasion you may receive a strange attachment in your email called Winmail.dat.
When you try to open it Windows will not let you, and the person sending it
to you has no idea what it is. Do not worry, there are many people who have
this same problem. The Winmail.dat is sent by users who use Microsoft Outlook
as their email client and who have the send as Rich Text setting enabled. The
Rich Text setting allows for all the original formatting including colors and
fonts to be seen by the recipient of the email. The problem is that this is
only useful for recipients who use Microsoft Outlook. If you are using Outlook
Express, Netscape Messenger, Eudora, or a myriad of other email clients, then
you will instead receive the Winmail.dat attachment.
How to stop sending winmail.dat files
If you use Microsoft Outlook as your mail client and have been receiving complaints

are guaranteed that everyone will be able to receive your emails as intended.
