You will need to configure an application signature.  See the following thread;

Blocking IM is a nightmare for any network administrator.

Try to enforce a written policy and let users know the consequences of breaking the rules. Another way is to deploy firewall client and add the MSN executable file to the list of blocked files.

Let me know if it works.

changing the executable file name will make the application accessable again.

the best way is to block by signature.

follow the following and u will not have any problems :

http://www.isaserver.org/articles/2004blockp2pim.html

and the signature from http://forums.isaserver.org/HTTP_Signatures_-_NO_QUESTIONS_-_JUST_SIGNATURES_PLEASE/m_2002015478/tm.htm as stated in a previous post.

if after doing this RIGHT , and MSN is still working then for sure u are having problems in ur configuration .

Elmajdal got the point. I do block IM by app signature. It's the simplest way to accomplish this task and have been working pretty well. Yet there are other ways to do that, one of them i've already explained in older post.

I havent found msn 8 signature yet.
