I have hit a wall trying to get Outlook Anywhere to work and I am at a roadblock (Outlook 2007, Exchange 2007, fully patched, rollup update 9). The symptom is that when doing the autodiscover it repeatedly asks for the login credentials. The output from testexchangeconnectivity.com is: Attempting to test Autodiscover for EMAIL REMOVED Successfully tested Autodiscover Test Steps Attempting each method of contacting the AutoDiscover Service The AutoDiscover Service was successfully tested.
