Tip: Use Group Policy to Configure Outlook Junk E-mail Filtering

Outlook 2010 offers a number of options for how you want to handle junk e-mail, letting you further increase security in your environment. By default, Outlook 2010 has the following Junk E-Mail Filtering settings:
  • Junk E-mail protection level: Set to LOW
  • Permanently delete Junk E-mail: Set to OFF
  • Trust E-mail from Contacts: Set to OFF
To configure Junk E-Mail Filter settings, you can use the Office Customization Tool (OCT) or Group Policy. OCT lets you establish the default configuration, but allows users to change settings. Group Policy, however, lets you enforce your settings.

To configure Outlook 2010 settings using group policy, you need to download and load the Outlook 2010 template (Outlk14.adm). You can get this as part of the Office 2010 Group Policy Administrative Template files, available here. For details details on downloading and installing the Office 2010 Administrative Template files, see Use New Group Policy Settings to Manage Office 2010.

Once you’ve added the new template files (including the Outlk14.adm file), open the Group Policy Editor and navigate to User Configuration\Administrative Templates\Microsoft Outlook 2010\Outlook Options\Preferences\Junk E-mail.

Here, you’ll find a number of settings that can be configured. For instance, you can choose to Hide Junk Mail UI, increase or decrease the Junk E-Mail Protection Level, or enable the option to Permanently Delete Junk E-Mail. Double-click an option to open its settings dialog.

Note that to use your Junk E-mail settings, you need to enable the Junk E-Mail Import list setting in the Outlook clients. To do this using the OCT:
  1. Open the OCT and go to the Modify user settings page.
  2. Under Microsoft Outlook 2010\Outlook Options\Preferences\Junk E-mail, double-click Junk Mail Import list.
  3. Click Enabled.
  4. Click OK.
  5. Complete other Outlook 2010 or Microsoft Office 2010 configurations in the OCT, and on the File menu, click Save to create the customization file that you can deploy to users.
