On a new Exchange 2010, I am able to connect from OWA but unabale to setup the Outlook profile. Getting the error
The action cannot be completed. The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action.
Ports 80 and 443 are open.
What are the additional port to be open so Outlook can successfully connect to Exchange?
What about the ports below are they required?
* TCP End Point Mapper (TCP/135)
* Dynamic RPC port range (6005-59530)
* 389/TCP/UDP (LDAP), 3268/TCP (LDAP GC), 88/TCP/UDP (Kerberos), 53/TCP/UDP (DNS),
