I'm currently publishing OWA/ActiveSync/etc.. through Forefront TMG.
The rules have been setup following guides from isaserver.org
Also using http redirect to https.
We use forefront for both internal and external access to mail.domain.com and autodiscover.domain.com
The issue lies in the inability to browse to the /EWS directory and see Exchange.asmx. It is something on TMG because if i set host files directly to the CAS box i can browse and see the xml file. I also can see fre/busy etc.. when using the hosts file but not when pointed to TMG. I should add that i get a 403 error when its pointed to forefront.
It also seems to be affecting outlook anywhere and anything not OWA/ActiveSync
I've verified in TMG a dozen times the settings and everything appears correct. Has anyone see this before that could offer some help?
