Outlook tries to protect you from opening certain types of attachments, even if you know they're safe. A registry change puts you back in control.
How do I force Outlook to open "potentially unsafe attachments" that I know are ok?
As discussed in an earlier article Outlook tries to protect you from viruses by blocking access to files which have certain extensions like ".exe" for example, because they could carry a virus and infect your machine.

Microsoft's official recommendation is that you have whomever sent you the file rename or zip it and send it again. And to be honest that's probably still the safest approach overall.
However that's just not an option sometimes. Fortunately there is a registry setting you can add that will instruct outlook to treat extensions that you specify as safe.
Before we go mucking about in the registry I'll caution you that the registry is a critical component of the operating system, and it's possible to render your system totally useless if you make the wrong changes. Microsoft provides instructions for backing up the registry here.
That having been said, the steps I'm about to outline are relatively simple if you follow along carefully.
HKEY_CURRENT_USER Software Microsoft Office 11.0 (Office 2003. For Office XP, expand "10.0") OutlookExpand each entry by clicking on the boxed plus sign to it's left. If that's a boxed minus sign then it's already expanded.
Remember: once you have enabled access to a particular file type, you are assuming responsibility for making sure that an attachment is safe before you open or run it.
