So, currently, those are the two IP addresses is use by that host name. If you block those, you'll block access to everything using the MS passport service, including Messenger, MSN, Hotmail and anything you need to log in to get at Microsoft.
If you have your own DNS server, you might be able to put in a dummy entry for this host, so that it will never resolve to an external IP address.
As with many IM packages, it's almost easier to remove the software than to try to block it at the firewall...
