OWA External Forms based authentication

I have a multi site Exchange 2010 deployment with a TMG server in both sites as well as 2 CAS servvers and 4 hub/mailbox servers in each site.  It is going to be an active-active setup and I am currently using Basic and Windows integrated auth for OWA so that I get a single sign on for internal users. I also have cross site redirection set to silent.

Here is my issue,  I would like the external redirection to work as smoothly as the internal and I don't think I can do that without Forms based auth.  How do I keep the internal experience the same and implement FBA for the external users?

Thanks in advance.

Hello,

When you setup the Exchange publishing rules in TMG, you can choose FBA. The TMG server actually does the FBA authentication so you can still use Basic/NTLM inside your network. Here is a whitepaper that describes how to use TMG to publish your Exchange server - http://www.microsoft.com/en-us/download/details.aspx?displaylang=en&id=8946
