====== Turn off TNEF (AKA winmail.dat) in Outlook ======
I hate that Outlook doesn't send proper emails and always seems to want to put emails inside a winmail.dat attachment. Even though most mail clients/anti-virus/anti-malware products now understand it, I still prefer to turn off the setting in Outlook and let it revert to "standard" formatted emails...
