Can't Open Attachments in Outlook Express

Not being able to open attachments in Outlook Express is a common problem after updating Internet Explorer.  That's because Internet Explorer and Outlook Express are tied together and by default, a security setting is configured to prevent you from opening potentially harmful attachments. Only problem is that this setting prevents you from opening ALL attachments. 

To fix  the problem, follow the steps below:
  1. Open Outlook Express
  2. On the menu, select TOOLS and then OPTIONS (a small window till open)
  3. Click the SECURITY tab on the newly opened window
  4. Uncheck the box that reads, "Do not allow attachments to be saved or opened that could potentially be a virus".
  5. Click the OK button to save the changes and close the window.

 
That should fix the problem.  Try opening your attachment again.  
If this didn't fix the problem ... there may be another security setting somewhere else that needs to be reconfigured.
