Missing root certificates

This policy setting controls how Outlook 2007 functions when a root certificate is missing.

If you enable this policy setting, you can choose from three options that determine how Outlook 2007 functions when a CRL is missing.

- Neither Error nor Warning. This option displays neither an error nor a warning, and enforces the default configuration in Outlook 2007.

- Warning. This option ensures that Outlook displays a warning message when a CRL is missing.

- Error. This option ensures that Outlook displays an error message when a CRL is missing.

If you disable or do not configure this policy setting, users are not prompted with a warning or an error when a root certificate cannot be located.

Supported on: At least Windows Vista
