Question : Owa acces fails

I Really dont know anymore where to look, I have a Exchange server With Mail role and CAS.
Then i Have my Forefront TMG 2010 server. I published the Owa, I used the Spilt DNS, I set the certificates, but NOTHING is working and i dont know where to look, The adres from outside the network DOES NOT WORK, Internally i Get a Server Error message. But when i use the internal name for the OWA it works...   Please help me?!

Answer : Owa acces fails

This is Exchaneg 2007 correct?

So you can get to the server when you go to:

http://server/owa or https://server/owa

Firstly, we have to change the Forms based Authentication (FBA) on Exchange Server site, because TMG also uses FBA and the settings enabled on TMG and Exchange will result in conflicts.


Please follow this guide on how to publish OWA through Forefont TMG
