Opening blocked attachments in Outlook by aznluvsmc
Posted: 20 Apr 04

Microsoft Office's Outlook was designed to block certain file extensions from opening due to possible malicious code.  A simple edit of the registry will allow you to specify which file attachments Outlook should not block.

1) Open regedit
2) Goto HKEY_CURRENT_USER\Software\Microsoft\Office\10.0\Outlook\Security
3) Create a new String value called Level1Remove
4) In the Value Data field type the file extension you wish to unblock.

To specify multiple file extensions separate each extension with a semicolon.  Ex:  .mdb;.bat;.exe
