How to block hotmail without affecting outlook.com

[Disease]

Anyone know of a way? It seems to me that because they both use the live.com address you can't have one without the other.

 

I go to all the trouble of setting up a closed campus system with live@edu and I hand the students access to hotmail at the same time.

 

I am using vanilla ISA 2006

This is only possible with HTTPS interception AFAIK - as you need to be able to do URL matching in order to hit the right levels of granularity.
