Uninstall Client Access From Exchange 2010

using Control Panel under programs select uninstall a program, selecy Exchange 2010 and then click Change.
Uncheck the Client Access role and complete the wizard.

That does not work.  I am not able to uncheck the Client Access Role

You sure you are clicking change?

Yes I seleced change

OK from a command prompt run:

setup.com /mode:uninstall /roles:ca

From the Exchange 2010 installation media

wonderful.  Well I ran the setup.com/mode..... and now my Outlook is not working.  HELP!!!!

here is the error I am receiving when I try to open Outlook

It wnot be because you just uninstalled the CAS role.

Can you change your outlook profile to the new server?

No it does not work with the new server.  I reinstalled the CAS and it is still not working please help.  This is critical.  BTW OWA is working though.

What error do you get on the outlook?

When you open it up it says the connection to the microsoft exchange server has been restored and then I get the attached error message

There is no error attached?

The error reads " Cannot start Microsoft Office Outlook, Cnnot open the Outlook window.  The set of folders cannot be opened.  Microsoft Exchange is not avialalbe or there are network problems or the Exchange computer is down for maintenance"

And what does the detail of the outlook profile say? Can you change it to be the new CAS server?

You will also need to update the Set-MailboxDatabase -RPCClientAccessServer value for the mailboxes.

No I cannot change it to the new server.  It keeps defaulting back to the old server.   I want to put everything back the way it originally was how can I do this?

This did not work.  I am getting the following errors:

[PS] C:\Windows\system32>Set-MailboxDatabase 0744773635 -RPCClientAccessServer haliserv3
The operation couldn't be performed because object '744773635' couldn't be found on 'HALISERV2.hali88.org'.

nevermind.  I put entered it as "Mailbox Database..."   And it seems to be working now.  Let me just double check

Ok everything seems to be working fine now.  I am a little concerned though.  It was working fine after I switched the CAS to the new server and then the old server rebooted itself 2 times and when it came back Outlook still was not working.  I did not do anything and then it started working again.  Very strange, but I need to keep an eye on this.  I will be out of the office tomorrow.  I will check back on Monday and update my situation.

Have you uninstalled the old CAS server?
It will take a while for all the clients to update but that script will make them all re-configure to use the new CAS server.

No I did not uninstall the Old CAS server.  I did not want to do anything since everything was working fine.  I will attempt another uninstall next week.
