How to Allow Blocked Attachments in Outlook 2007

By default, Outlook 2007 prevents the user from downloading email attachments with file types that could potentially carry viruses and be unsafe. This is due to the fact that it is possible to receive unsafe files even from someone you know, because you have no way of knowing whether their computer is infected by a virus. However, there may be situations in which you want to remove this protection because you know what a file is and need to be able to open it. Allow blocked attachments in Outlook 2007 if you are aware of the potential risks and want to download a file anyway.

Instructions

1. Press the Windows logo and "R" keys simultaneously to display the "Run" window. Type "regedit" in the window and press "Enter" to launch the Windows registry editor.

2. Use the folder tree on the left side of the window to navigate to "HKEY_CURRENT_USER," "Software," "Microsoft," "Office," "12.0" and "Outlook."

3. Right-click the "Outlook" folder and click "New" and "Key." Type "Security" and press "Enter," then click the newly created "Security" folder.

4. Right-click in the open area on the right side of the screen and click "New" and "String Value." Type the name "Level1Remove" and press "Enter." Double-click the new "Level1Remove" registry key to open it in a new window

5. Type the extension of the file that you are attempting to access, including the period before it, for example, ".com." If you would like to remove Outlook's block on other file types, separate them with a semicolon: ".com;.pif." Click "OK" to save your changes.

6. Exit the registry editor and restart your computer. After the computer starts, launch Outlook. If the file that you are attempting to access is still blocked, ask the sender to email it to you again.
