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

Glen Knight

It wnot be because you just uninstalled the CAS role.

Can you change your outlook profile to the new server?

ASKER
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.

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"
Glen Knight

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.

ASKER
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?

nevermind.  I put entered it as "Mailbox Database..."   And it seems to be working now.  Let me just double check
rsilver24

ASKER
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.

ASKER
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.
