I've been struggling with this for days. I have Exchange 2010 SP1 with roll up 2 on a server 2008 R2. The server is in a data center and I cannot get Outlook Anywhere to work with Outlook 2010. I am putting mail.mydomain.com, select connect using http on fast and slow networks, and basic authentication. I have entered the registry key to disable IPv6 and removed the thing from the hosts file. This is driving me absolutely insane but I can't tell my boss that he can't use Outlook from his house...
Everything passes on testexchangeconnectivity except 1 warning:
ExRCA can only validate the certificate chain using the Root Certificate Update functionality from Windows Update. Your certificate may not be trusted on Windows if the "Update Root Certificates" feature isn't enabled
This is a new server. The OS is Windows Server 2008 R2. The server is the domain controller and is the only server in the domain. It has Exchange 2010 SP1. All updates have been installed including update roll up 2. My certificate is from godaddy and is the one that allows 5 domain names. I have read through every article I can find and there is no answer to my problem. Do I need to call MS support?
