There are two steps involved in con guring Outlook 2007 attachment security using Group Policy. First, you con gure the security settings for attachments and custom forms. Once you are satis ed with the con guration, you con gure Group Policy as the method that Outlook 2007 uses to obtain security information.

Security settings applied via Group Policy do not take effect immediately. Changes will be made after the computer receives a Group Policy update (usually at the next logon) and consequently starts Outlook 2007. Even when a computer receives refreshed Group Policy automatically, settings will not apply to Outlook 2007 until the next time it is started.

You manage Outlook 2007 attachment security using the Outlook 2007 administrative template (Outlk12.adm) which is found in the Admin Pack (adminpak.msi) and the Group Policy Editor.

For detailed information about using Group Policy templates, go to: support.microsoft.com/ kb/924617.

To install the administrative template, follow these steps:

Download the administrative templates from www.microsoft.com/downloads/ details.aspx familyid=92d8519a-e143-4aee-8f7a-e4bbaeba13e7. Save the le in the AdminPak directory. 3. Open a Command Prompt window, and switch to the AdminPak folder. 4. Type adminTemplates /extract:\adminPak , and then press Enter. 5. Follow the prompts to extract the administrative templates. To add the administrative template to Group Policy, follow these steps: 1. On a server with the Windows Server administrator tools installed, click Start, Run, type gpedit.msc in the Open box, and then press Enter. 2. In the Group Policy editor, browse to User Con guration/Administrative Templates. 3. Right-click Administrative Templates, and then select Add/Remove Template.

To con gure the Outlook 2007 attachment security settings, follow these steps: 1. On a server with the Windows Server administrator tools installed, run Group Policy by clicking Start, Run, typing gpedit.msc, and then pressing Enter. 2. Browse to User Con guration\Administrative Templates\Classic Administrative Templates (ADM)\Microsoft Of ce Outlook \Security\Security Form Settings\ Attachment Security. 3. Con gure the settings using this list as a guide. The default setting is Not Con gured for all items in this policy: Enable Display Level 1 attachments if you want to allow Outlook 2007 users to see and open Level 1 attachments, effectively setting the attachments to Level 2. To allow Outlook 2007 users to change Level 1 attachments to Level 2, enable Allow Users To Demote Attachments To Level 2. If you want to surpress the warning that usually appears when a Level 1 attachment is sent, enable Do Not Prompt About Level 1 Attachments When Sending An Item.

To disable the warning that normally appears when the user closes an item that contains a Level 1 attachment, enable Do Not Prompt About Level 1 Attachments When Closing An Item. If you want to let Outlook 2007 users open embedded OLE objects (such as Microsoft Of ce Word 2007 documents, Excel 2007 spreadsheets, and other documents), enable Allow In-Place Activation Of Embedded Ole Objects. Enable Display Ole Package Objects to show embedded OLE objects in e-mail messages and allow users to open them. You can block additional le types by enabling Add File Extensions To Block As Level 1. Specify a list of le name extensions, without periods and separated by semicolons (;), in the Additional Extensions eld. You can specify a list of le name extensions to remove from the Level 1 attachment list by enabling Remove File Extensions Blocked As Level 1 and entering the list in the Additonal Extensions eld. To add le types to the Level 2 list, enable Add File Extensions To Block As Level 2, and then enter a list of extensions. Enable Remove File Extensions Blocked As Level 2, and then specify a list of le name extensions to remove from the Level 2 attachment list.
