Hi

Have installed Exch2010 CAS and MB roles into an AD2008 network that currently has a functional Exch2007 setup. Certificates etc are all installed (we have proper wildcard and mail.domain.com certs that we use)

OWA and Activsync clients (tested with Winmo and iPhones) all works fine but Outlook clients cannot connect. Attempted to test connectivity on the Exch2010 CAS server (test-OutlookConnectivity) returns errors saying it cannot find the Test Mailbox extest_somenumbers@mydomain.com

The test from the test website comes back with
Attempting to ping RPC Endpoint 6001 (Exchange Information Store) on server mail.mclachlandigital.com Failed to ping Endpoint Attempting to ping RPC Endpoint 6001 (Exchange Information Store) on server mail.mclachlandigital.com Failed to ping Endpoint

Two questions.

1. Did you run New-TestCasConnectivityUser.ps1 from the Scripts directory yet to create the necessary test mailboxes?

2. Did you enable OLA on the CAS servers? If you didn't then they won't be listening on 6001.

Have you tried running https://www.testexchangeconnectivity.com/?

On your Outlook client if you hold down Ctrl while right clicking the Outlook icon in the task bar you should see two new options in the menu for testing your connection. Is Outlook trying to connect to the endpoints you think it should be connecting to?

Hi,

You can use RPCCFG tool to check whether the valid ports registry key is configured correctly on CAS server. You should get result like below:

Note: MB is the netbios name of mailbox server and the mb.lab.com is the FQDN of the mailbox server

Server Name Port Settings

-----------------------------------------------mb 6001-6002 6004

mb.lab.com 6001-6002 6004

c. You can use RPCDump tool to check whether the 6001, 6002 and 6004 ports are listened by Mailbox Server:

a4f1db00-ca47-1067-b31f-00dd010662da represents the Information Store which should listen 6001 port

f5cc5a18-4264-101a-8c59-08002b2f8426 represents the Directory Proxy Service which should listen 6004 port

1544f5e0-613c-11d1-93df-00c04fd7bd09 represents the Directory Referral Service which should listen 6002 port

d. You can also use RPCPing tool to check whether the issue occurs when client connects to CAS server or the CAS server connects to backend mailbox server:
