Never mind, I think I see those options under Smart Defense. The only
problem is, for that to work I believe the only protocol you can allow
outbound is HTTP, otherwise the IM services would use any other
available ports. I wonder if they could use the HTTPS port too? I
don't know how anyone can only allow HTTP and not HTTPS...

This is one issue AI specifically adresses. Unfortunately, blocking the
networks is not an effective means of dealing with this issue. It can
temporarily, and in some cases permanently shut off one particular
messaging service. I equate this to trying to use your own list to block
adult websites. SmartDefense addresses this issue by intelligently
inspecting data transactions, and recognizing the messaging protocol
itself. As new services come out, you have the ability to filter and
identify them using regular expressions.

If you're using AI I guess you could do it from SmartDefense. Otherwise
you must block the Messenger server networks (addresses have been posted
here previously).
