TMG 2010 - Autodiscover fails on Exchange 2010
Hi guys,
I'm having trouble with the autodiscover feature in Exchange 2010, users can't setup Outlook from outside the domain network.
I ran the Microsoft Connectivity Test and it failed:
Our mail server is behind Forefront TMG 2010, but that path is published.
I don`t understand why TMG is blocking connections to that URL if it`s published on the rule.
Any help would be appreciated.
Regards.

Hi
Not totally my cup of tea but from what I understand isa creates a standard rule denying everybody from everywhere. Did you create a new access rule like described on this link?

Hi,
Did you try the "Test Rule" button on the TMG to verify that TMG is able to reach internal server ? What is the result ?
Also, cnayou show us the "To" tab settings, the "Authentication Delegation" tab settings and the "Bridging" tab settings ?
Do you publish also OWA with the smae TMG and does it work ?
