Disabling Security in Microsoft Outlook

2 of my friends have tried to send me .exe files through my email account that i ok'd. Unfortunately, when i go to read the email it has the text, but the attachment says 'Outlook blocked access to the following potentially unsafe attachments: name-of-attachment.exe'

I looked around in settings but found no setting similar. I also tried right-clicking on the attachment and it says 'No help topic is associated with this item.'

Anyone got any ideas how to get rid of this annoying security measure?

Break open regedit and navigate to this:
HKEY_LOCAL_MACHINE\Software\Microsoft\Office\9.0\Outlook\Security

Inside will be values.. AddWarningFileTypes and RemoveWarningFileTypes

Each value has a uniuqe set of data, which happend to be semi-colon delimited extensions. Simply add EXE to RemoveWarningFileTypes and/or remove it from the AddWarningFileTypes

I believe this question was asked earlier, on the old forum perhaps... A while back. So there's a thread out there with more information if that doesn't work.
