An update is available to enable the control of the file transfer through the Access Edge service in a Lync Server 2010 environment

This article describes an update that enables environment administrators to separately define the file transfer policy for common extensions and the URL style link files between users on the local area network and users that connect through the Access Edge server in a Microsoft Lync Server 2010 environment. This update lets environment administrators apply specific Intelligent Instant Message Filter (IIMF) rules to a registrar or to an Edge Server pool. After the IIMF rules are applied, the environment administrators can block all file transfers through the Edge Server pool and allow file transfers between registered users.

Note The external users include the federated users.
