Redirecting your Exchange Server to use the External DNS Name

Redirecting your Exchange Server to use the External DNS Name




To update your Exchange 2007 or Exchange 2010 server you will need to run the following commands from the Exchange Management Shell and replace the Server running the Client Access Role with your external domain name. These commands update the URL for the Autodiscover service, Exchange Web Services (EWS) and the OWA Web-based Offline Address book respectively.

Before running these commands you will just need to check make sure a DNS record exists mapping the IP Address to the Exchange Client Access (CAS) server.

Note: Each of these commands below should be run on a single line in the Exchange Management Shell (EMS):




 




mail.customerdomain.com






Get-ClientAccessServer | Set-ClientAccessServer -AutoDiscoverServiceInternalUri https://mail.customerdomain.com/Autodiscover/Autodiscover.xml

Get-WebServicesVirtualDirectory | Set-WebServicesVirtualDirectory -ExternalUrl https://mail.customerdomain.com/EWS/Exchange.asmx -InternalUrl https://mail.customerdomain.com/EWS/Exchange.asmx

Get-OabVirtualDirectory | Set-OabVirtualDirectory -ExternalUrl https://mail.customerdomain.com/OAB -InternalUrl https://mail.customerdomain.com/OAB

Get-ActiveSyncVirtualDirectory | Set-ActiveSyncVirtualDirectory -ExternalUrl https://mail.customerdomain.com/Microsoft-Server-ActiveSync -InternalUrl https://mail.customerdomain.com/Microsoft-Server-ActiveSync

Get-EcpVirtualDirectory | Set-EcpVirtualDirectory -ExternalUrl https://mail.customerdomain.com/ecp -InternalUrl https://mail.customerdomain.com/ecp

Get-OutlookAnywhere | Set-OutlookAnywhere -ExternalHostname mail.customerdomain.com -InternalHostname mail.customerdomain.com -ExternalClientsRequireSsl $true -InternalClientsRequireSsl $true -DefaultAuthenticationMethod NTLM
