Changing Internal URLs in Exchange 2010

I have a question on the issues of changing the internal URLs for autodiscovery, ActiveSync and the like on my Exchange 2010 server

My Active Directory domain name ends in xxx.local, and the Exchange URLs for internal users also end in xxx.local - the URL for external users ends in xxx.org.  My SSL cert therefore has xxx.local and xxx.org as subject alternative names.  This cert is up for renewal but under the new guidelines I cannot use internal domain names as subject alternative names.  This means I have to change all the internal URLs to xxx.org.

I know how to change the URLs, and I have split DNS already set up to handle name resolution.  Is there anything I need to do with the email clients (Outlook 2010)?  Will the clients automatically pick up the new settings and reconnect?  Are there any other issues I need to be aware of?

Your help is greatly appreciated.

No - once you have added the new certificate without the .local names in and made the URL changes to Exchange, there is nothing to do on the client side at all.

In case you want to script the URL changes, this is what you will need:

Set-AutodiscoverVirtualDirectory -Identity * -internalurl “https://mail.domain.com/autodiscover/autodiscover.xml”
Set-ClientAccessServer -Identity * -AutodiscoverServiceInternalUri “https://mail.domain.com/autodiscover/autodiscover.xml”
Set-webservicesvirtualdirectory -Identity * -internalurl “https://mail.domain.com/EWS/Exchange.asmx”
Set-oabvirtualdirectory -Identity * -internalurl “https://mail.domain.com/oab”
Set-owavirtualdirectory -Identity * -internalurl “https://mail.domain.com/owa”
Set-ecpvirtualdirectory -Identity * -internalurl “https://mail.domain.com/ecp”
Set-ActiveSyncVirtualDirectory -Identity * -InternalUrl "https://mail.domain.com/Microsoft-Server-ActiveSync"

Just change mail.domain.com for your Public name which is included in your SSL certificate.
