Dear Sir ,

Ask two question ?

1. How do I deny the IM attach file in CSA MC ?

2. How do I deny skype and skype attach file in CSA MC ?

Thanks

You can use a dynamic application class to detect when skype is running, either by its network traffic, or its name, and then apply general file access control rules for that application class.
