    I work for a big company and we are currently testing out Lync Server 2010 and may decide to purchase it but there is an isssue, we want to control employee usage and we want to disable the file transfer option for certain people or by group, for example IT department can do file transfers but HR cant.

     

    How do i achieve this?

     

    CMD

    Hi Cathal,

    To disable File Transfer in the Lync Client use the following. This will disable it for all the users but you could create a seperate Conf Policy for that if you like.

    Set-CsConferencingPolicy -Identity global -EnableP2PFileTransfer $False

    Regards

    Hi,CMD,

    You can look at Client policies,they help determine the features of Microsoft Lync 2010 that are made available to users; you can give some users the right to transfer files while denying this right to other users with different client polocies.More syntax  please check the links below:

    New-CsClientPolicy  http://technet.microsoft.com/en-us/library/gg425949.aspx

    Set-CsClientPolicy  http://technet.microsoft.com/en-us/library/gg398300.aspx

    Grant-CsClientPolicy  http://technet.microsoft.com/en-us/library/gg412942.aspx

    And here is a thread indicate that you could do this in OCS with GPO, this would probably still have the desired effect on Lync clients.

    Hope this useful!

    Regards,

    Hi, Thanks for your reply, i was able to access the "prevent file transfer" in the OCS but this is only for all users, how can i assign it to single users or groups? CMD.

    Hi,CMD,

    You can use New-CsClient policy to create a policy to block file transfer then use Grant-CSClientPolicy to grant the policy to the users or site you want to block file transfer.

    You can look at Elan Shandow's blog to see how to configure client policy at site level or user level for more details.

    http://www.shudnow.net/2010/10/28/lync-2010-client-policies/

    Additionly,some cmdlets about file transfer for your reference.

    You see there's is no command in the "New-CsClientPolicy" to block file transfers, i am looking at this site: http://technet.microsoft.com/en-us/library/gg425949.aspx

     

    The only commmands that have anything to do with file transfers is:

    EnableUnencryptedFileTransfer: When set to True, users will be allowed to exchange files with external users whose instant messaging software does not support encrypted file transfers.

     

    I have tried applying this to a user and it makes no difference..as i expected. Is there any other way??

     

    Regards, Cathal.

    Actiance provide a product called Vantage which allows compliance controls to deployed based on AD groups, including blocking file transfers. If Lync is not sophisticated enough for your needs regarding compliance, Vantage covers many options.
