opening DAT files

can I open and e-mail archive DAT file with Entourage?

A DAT extension is s generic 'data' file - where are these DAT files
originating?

If you mean 'winmail.dat' files then:

Winmail.dat and/or application/ms-tnef files are sent by Windows users of
Outlook or Exchange who have their mail clients set up to use ŒRTF¹ instead
of plain text or HTML.

Usually they only contain a styled text version of the message you have just
read in plain text, but they can contain encoded attachments that you can¹t
usually get to.

Fortunately, there is an excellent little application that lets you read
these files and extract the attachments, called ³TNEF¹s Enough², by Josh
Jacob. Here¹s a link that should let you find it on VersionTracker:

ilter=MacOSX&search=tnef& ;x=14&y=8

Better still, contact your correspondent and ask them to reset their mail
client prefs to use plain text, or at worst, HTML. Outlook 2003 has a
setting found under Tools\Options "Mail Format" tab, INTERNET FORMAT button.
Inside this dialog box, the Outlook user has the option of converting
messages sent outside the Exchange server to HTML, plain text or unchanged.
