As noted elsewhere, this is the result of overzealous AV software. Try
zipping the file before attaching it.

What would cause Word 2007 created files to become .dat files?
Full story: When I receive a file as an Outlook attachemnt it arrives
with the DAT extension. The sender swears the file was created and saved
with Word 2007.
Nonetheless, it can be opened with Word and appears to be fine.
TIA
