Known issues with this security update

After this update is applied, you may experience issues with S/MIME certificate verification in Microsoft Outlook. This issue is caused because the update disables remote intermediate certificate fetching in Outlook.If you experience these issues or if you are working in an enterprise installation that requires the retrieval of remote certificates referenced in an authority information access extension, a registry key can be set to enable remote intermediate certificate fetching in Microsoft Outlook.Warning Setting the registry key to enable remote intermediate certificate fetching will remove the protections provided by this update.Important Follow the steps in this section carefully. Serious problems might occur if you modify the registry incorrectly. Before you modify it, back up the registry for restoration in case problems occur.To enable remote intermediate certificate fetching in Outlook after this update is applied, set the following registry key value:

Registry location: HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\14.0\Outlook\SecurityDWORD name: EnableAIACertExtensionValue data: 1Notes

  • You may have to create the Security subkey and the EnableAIACertExtension DWORD entry if they do not exist.

  • To disable the evaluation, set the Value data to 0 (0 is the default).

Additionally, you can apply this registry key change across domains by using Group Policy. For more information about Group Policy, see the TechNet article, Group Policy collection.
