SYMPTOMS

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.

RESOLUTION

To resolve this issue, install the following cumulative update:
2514981 Description of the cumulative update for Lync Server 2010, Core Components: November 2011
After the update is installed, the environment administrator can run one of the following commands in Lync Server Management Shell to apply a client policy:
  • To block URL style links:
    New-CsImFilterconfiguration -Identity EdgePoolIdentity -BlockFileExtension $True -Action Block -Enabled $True
  • To block the transfer of files with common extensions:
    New-CsFileTransferFilterConfiguration -Identity EdgePoolIdentity -BlockFileExtension $True -Action Block -Enabled $True
  • To block the transfer of all files:
    New-CsFileTransferFilterConfiguration -Identity EdgePoolIdentity -BlockFileExtension $True -Action BlockAll -Enabled $True
Note In this command, EdgePoolIdentity is a placeholder for the identity of the Edge Server pool that is returned by running Get-CsService –EdgeServer command. You can also use the FQDN of the Edge Server pool instead of the identity.
