Through this article we will talk about enabling and disabling file transfer filtering.

If you don't want to allow the OCS users to do file transfer, you can disable it through Intelligent IM Filtering. Intelligent IM Filtering is an application which gets installed with OCS itself.

You can even allow\block certain types of files. For example if you want to block only executable files to be transferred, you can do so!

Other thing is, If you want to disable file transfer using office communicator and at the same time you want to let Live Meeting client users to transfer the files then how to achieve this! Obviously we can... we will discuss about how to do in this article.

Situation: You want to block file transfer through any types of OCS clients.

Solution: Application Properties => Intelligent IM Filter

Click Block all file Extensions. This will block any kind of file transfer for live Meeting and Office Communicator clients. If you want to block only files with particular extensions, you can select the second option in the following figure.

Situation: You want to block file transfer through only Office Communicator 2007, but you want the Live Meeting 2007 users to be able to transfer the files.

Solution: Allow File transfer using Intelligent IM Filter as follow.

And configure the following two Group Policies.
