My email attachments are suddenly downloading as .dat file?

[Guest]

How can I prevent my attahcments from downloaing as .dat files? I have to
save the attachment to my desktop then right click, open with, then choose
the correct program. This never happened before!!!

If it is the winmail.dat file then the sender should change their settings:

What version of Outlook are you using?
Is it all emails?
Is it from different senders (i.e. what happens if you send yourself an
attachment)?
What is the naming convention of the .dat files?
Do you have any anti-virus programs or spam programs running?
