Am getting the following error when testing autoconfiguration in Outlook 2010. I started checking this because we are receiving errors when trying to set the Out Of Office Assistant. This is all inside the LAN, no firewall is in play. Client is Outlook 2010, mailbox is on Exchange 2010, sp2. I am able to correctly resolve the name autodiscover.domain.com. If I manually browse tohttps://autodiscover.oblon.com, I am redirected to Outlook Web Access. If I manually browse tohttps://mail.domain.com/Autodiscover/Autodiscover.xml, I get the 403 Forbidden. Any idea which settings I should be examining in Exchange Management Console or the Exchange Management Shell or even IIS? I'm stumped! Many thanks in advance.
