Outlook not working after Group Policy Firewall Settings

I have a group of PCs in a domain environment that we want to lock down except for a few applications.  I am using Group Policy to configure firewall exceptions to allow these applications to work.

One of the allowed applications is Outlook.  We have a CASARRAY, and currently when I try to access Outlook it says that Exchange is offline and won't let me configure a new account.

In the GPO, I have rules configured for DNS & AD Domain Services.  For Outlook I created a rules that allow access to the CASARRAY with the following:

Outbound:
"389/TCP/UDP (LDAP)
3268/TCP (LDAP GC)
88/TCP/UDP (Kerberos)
53/TCP/UDP (DNS)
135/TCP (RPC netlogon)
80/TCP
443/TCP (SSL)"

Inbound
"TCP End Point Mapper (TCP/135)
Dynamic RPC port range (6005-59530)"

I am still unable to configure Outlook.  What am I missing?  Is there a different approach I should be taking?
