Problems when opening attachments

Issue encountered

When opening emails or email attachments from the GFI Archiver web interface, one of the following errors is encountered:

  • A Web filtering error specifying that the downloaded attachment is corrupted.
  • The downloaded attachment is opened in Internet Explorer® instead of its default application.

This may occur when a web filtering tool is installed between GFI Archiver server and Outlook Connector, and is blocking HTTP requests.


Configure the web filtering tool to allow all HTTP traffic generated from GFI Archiver server. Ensure that the GFI Archiver server’s IP address, NETBIOS name or DNS name are not blocked by the web filter. For more information, refer to:
