Block federation file transfer but allow internal to external user file transfer RRS feed

  • Question

  • In Lync 2013, to block all file transfers on the edge server you would use the following command:


    new-csfiletransferfilterconfiguration -identity edgeserver:pia-ls2013-ed01.widgets.com -action blockall -enabled $true

    I find this powershell but it will block all edge file transfer include internal to external file transfer.

    Any method the block federation file transfer only?

  • Hi Mick TT,

    You cant block file transfer for external users only im afraid, if you disable file transfer you disable for all users.

    You are able to prevent file download in meetings for federated and anonymous participants by changing setting in conferencing policy but i dont think this is what your after.

    I dont believe you can also add a file filter to the edge server role as in your PowerShell listed the identity should be the site name defined in SfB. You can set file filters at a site,Front End Pool and global level.

    Hope this helps.
