So today I had a issue with Outlook blocking email attachments and I had to make the change on a Terminal Server for 25 users.
Basically go into registry @ 'regedit' (run as admin, if you search for it)
Then navigate to this location depending upon your flavor of Office:
Verify that the following registry key for your version of Outlook exists.
Microsoft Office Outlook 2010HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\Security
Microsoft Office Outlook 2007 HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\Security
Microsoft Office Outlook 2003 HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Outlook\Security
Microsoft Outlook 2002HKEY_CURRENT_USER\Software\Microsoft\Office\10.0\Outlook\Security
Microsoft Outlook 2000HKEY_CURRENT_USER\Software\Microsoft\Office\9.0\Outlook\Security
Then just make a String key and call it 'Level1Remove' and click ok.
Then right click it and press modify and say you need to unblock a .url or a .exe you enter those in separated by a semicolin and no space like this : '.url;.exe' and press enter.
Restart Outlook if it's still open and whalla now you can open previous blocked attachments that Outlook automatically blocks by default.
We employ a twin Sonicwall Gateway barrier with different levels of border protection, so I'm not really worried about attachment having viruses since the Sonciwall's block them plus Kaspersky is awesome for client-based IPS with heuristic detection. -
with this being said if you don't have solid network security use this registry change with caution.
Hope this helps someone.
