WN11-UC-000020 - Zone information must be preserved when saving attachments.

Information

Preserving zone of origin (internet, intranet, local, restricted) information on file attachments allows Windows to determine risk.

Solution

The default behavior is for Windows to mark file attachments with their zone information.

To correct this, (for each user profile on the system) configure the policy value for User Configuration >> Administrative Templates >> Windows Components >> Attachment Manager >> 'Do not preserve zone information in file attachments' to 'Not Configured' or 'Disabled'.
