Revealing Blocked Outlook Attachments

Ever since Outlook 2000 SP1, Microsoft has felt it necessary to protect users from themselves by blocking potentially unsafe attachments from being executed. Outlook’s behavior is to receive the email and prevent the user from opening the MIME attachment by displaying a message.

Ironically, there’s no mechanism inside of Outlook’s UI or options to disable this feature. It’s a registry hack, and I’m often asked how to turn the feature off, or, to disable the blocking feature on specific file types. I had a need for the hack myself recently, so here it is again:

As the article suggest, this is a registry edit; people comfortable with editing the registry should be able to perform the steps with ease. If you’re not comfortable with editing the registry – or don’t know what that means – try to locate a computer pro to help you out. This hack will allow Outlook to permanently display attachments with file extensions you specify.
