.xls email attachments are arriving at the recipient as .dat file.
 

I am running Excel 2003 and yesterday I emailed (using Outlook 2003) twice to
different addresses at the same client with .xls attachments. Both times the
attachments arrived as .dat files. When I sent myself one of the messages as
a test, it arrived with the attachment OK and uncorrupted. Any ideas? is it
their virus protection maybe?

I would suggest that you are sending in Rich Text Format and your
clients are not using Outlook as their email client. Try sending using
plain text or HTML format instead.

Try sending in "Plain Text" format to all receivers.

Some email clients(Outlook Express for one) do not handle Rich Text Format and
change the files to *.dat

Think you'll find it's *all* email clients other than Outlook!
