Outlook Issues after CAS Move

June 4, 2012 By Damitha Anuradha Leave a Comment

Outlook Clients unable to connect to Exchange 2010 new Client Access Server after Client Access Server Role is Moved.

After installing new Client Access Server on your environment or If you uninstalled the old Client Access Server you will see outlook still trying to reach your old Client Access Server.

Even if you put the new Client Access Server FQDN/IP address in to the server name field, it will automatically resolve the old CAS server FQDN.

Server Description Server Name IP Address Operating System Application
Domain Controller dc.doitfixit.local 192.168.1.100 Windows Server 2008 R2 SP1
Standard Edition
Exchange CAS/HUB server
(Old Server)

Standard Edition
Exchange Server SP2
Exchange CAS/HUB server
(New Server)
cas2.doitfixit.local 192.168.1.105 Windows Server 2008 R2 SP1
Standard Edition
Exchange Server SP2
Exchange Mailbox Server ex1.doitfixit.local MAPI: 192.168.1.102

Exchange Mailbox Server ex2.doitfixit.local 192.168.1.103
Replication: 10.1.10.11
Windows Server 2008 R2 SP1
Enterprise Edition
Exchange Server SP2

I have installed new Client Access Server named “CAS2” in my Exchange 2010 environment. Let’s check the RPC Client Access Server by Exchange Management Shell.

Get-MailboxDatabase | fl name,*rpc*

As shown on above image after installing new Client Access Server, I have added cas2.doitfixit.local as a server name, but its automatically resolve old server name.

Now I am uninstalling old client access server (cas.doitfixit.local) and again check the RPCClientAccessServer. See now It has no value. (See the below image)

In this moment if you trying to configure outlook with auto configuration you will receive below error.

An unknown error occurred, error code: 0x80070057

In the same time you will receive below error in your new Client Access Server as well.

Log Name: Application
Source: MSExchange Autodiscover
Event ID: 1
Level: Error
Task Category: Web
Computer: <New CAS FQDN>
General: Unhandled Exception “User setting ‘PreferredSite’ is not available.”
Stack trace

If the Client Access server role was moved from cas.doitfixit.local to cas2.doitfixit.local, you can assign the mailbox databases with new RPC Client Access service by running below command.

Set-MailboxDatabase -Identity “DB01” -RpcClientAccessServer cas2.doitfixit.local

Again I executing Get-MailboxDatabase | fl name,*rpc* command to view current RPCClientAccessServer. CAS2.doitfixit.local is now associated with DB01 database.

Also we can perform this action for all Mailbox Databases on the server by running below command.

Get-MailboxDatabase -Server ex1.doitfixit.local | Set-MailboxDatabase -RpcClientAccessServer cas2.doitfixit.local
Get-MailboxDatabase -Server ex2.doitfixit.local | Set-MailboxDatabase -RpcClientAccessServer cas2.doitfixit.local

Lets check the RPCClientAccessServer

Now Outlook will connect to new Client Access Server successfully.

To view the connection status hold down the Ctrl key and click outlook icon in tray. And click connection status.

Now you can see outlook is connected to new Client Access Server.
