Hi there, I'm having trouble setting up Outlook 2010 security policies using Local Group Policy. I'm trying to set up some policies for attachment handling. I want to add file extensions to block as level 2 so that the user must save to hard disk before opening. I'm editing the following policies: User Configuration - Administrative Templates - Microsoft Outlook 2010 - Security - Security Form Settings Here I am editing the Outlook Security Mode to Use Outlook Security Group Policy. User Configuration - Administrative Templates - Microsoft Outlook 2010 - Security - Security Form Settings - Attachment Security Here I am editing the Add File Extension to Block Level 2, I enable and add extensions. Upon rebooting the computer I still find that Outlook is completely ignoring these policies. When I run the RSOP.msc I can see that the policies are being applied. I have searched the web extensible but can't find any reason for Outlook not picking up policies. Any help greatly appreciated.
