I have just implemented Exchange 2013 and migrated users to this new domain. We have purchased a Thawte Certificate for autodiscover.domain.org and mail.domain.org, however when my clients open Outlook we get an error stating

Security Alert
SERVERNAME.DOMAIN.LOCAL

2 Green Check marks

1. The security certificate is from a trusted certifying authority
2. The security certificate date is valid

RED X: The name on the security certificate is invalid or does not match the name of the site

Do you want to proceed?
YES

You get this because your internal url points to.local.
You need to update your internal url to point to.org

Change your urls using the steps below

Edit the FQDN in the following set of commands and then copy / paste them all into the Exchange Management Shell and that will sort the problem for you:

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

All the ones under internal url

For internal URLs:

$urlpath = Read-Host "Type internal Client Access FQDN starting with http:// or https://" Set-ClientAccessServer –Identity * –AutodiscoverServiceInternalUri “$urlpath/autodiscover/autodiscover.xml”
Set-webservicesvirtualdirectory –Identity * –internalurl “$urlpath/ews/exchange.asmx”
Set-oabvirtualdirectory –Identity * –internalurl “$urlpath/oab”
Set-owavirtualdirectory –Identity * –internalurl “$urlpath/owa”
Set-ecpvirtualdirectory –Identity * –internalurl “$urlpath/ecp”
Set-ActiveSyncVirtualDirectory -Identity * -InternalUrl "$urlpath/Microsoft-Server-ActiveSync"

Simple replace url path with your .org domain name
