Winmail.dat does not always mean that there is an attachment. It means 
that some one who has incorrectly configured their exchange server has 
allowed the iused of the Microsoft Rich Text for external emails and the 
formatting data is contained in the winmail.dat, not attachments.

Formatting data like outlook stationery, and horizontal rules and other 
formatting data.

You can safely delete them, but do it with a warning to the folks 
running exchange.

If the email had an attachment and was send from an incorrectly 
configured exvchange environment you wouild see 2 attachments, not the 
winmail.dat containing the 2nd attachment.
