So with a setup of 2 Exchange 2010 servers each being CAS/HUB/MBX, participating in a DAG and each being a member of the casarray outlook.contoso.com, i read that MS NLB is not supported on DAG members.
The goal of the deployment is to have FBA for both internal and external users,so we point internal users to the internal interface of Forefront TMG and use Forefront TMG FBA.
For now we have a DNS record for outlook.contoso.com that points to one of the CAS server. So i would like to make use of our Forefront TMG server to help load balance our 2 CAS cassary members.
I cant find any documentation on this. Is it possible to create a Publishing rule for Outlook.contoso.com (casarray)?

Yes, it's possible to make TMG to loadbalance 2 CAS servers.
My suggestion is: You should set up a seperate TMG server which handles the internal Exchange NLB traffic, as I believe it could bring heavy load for TMG, so you should not mix the internal NLB function with the existing TMG server.
