How to block file transfer and desktop sharing in Lync 2010 for Fedrated and Guest Users

Question

 
Dear,
Can anybody guide me how to restrict desktop sharing and file transfer for federated and Anonymous logins in Lync 2010.
I have tried to apply this policy through “Conferencing Policy”, but this gets applied to all users including corporate users.
Please help in this.

Hi,
As my knowledge, the CsFileTransferFilterConfiguration and setting in confercing policy are used to block transfer file between users. So if the policy is applied to user, the user would not transfer file with anybody. Since all Federation and Guest
Users access thought the Access Edge service, here is a update that helps to enable the control of the file transfer through the Access Edge service.

The update helps to define the file transfer policy between users on the local area network and users that connect through the Access Edge server in a Microsoft Lync Server 2010 environment. It helps protect Microsoft Lync Server 2010 deployment against
the spread of the most common forms of viruses with minimal degradation to the user experience.
