Script for Configuring Exchange 2010 Internal and External URLs

Ståle Hansen 8 Comments

[tweetmeme source=”stalehansen” only_single=false]In Exchange 2010 you need to set the Internal URLs for various services on the Client Access Server. Outlook 2007/2010 uses Autodiscover to connect to the Exchange server. If the Internal URLs are configured wrong you could get certificate errors when logging on to Outlook as well as errors when using free busy and oof services internally. Also when deploying Outlook Anywhere you need to configure the External URLs correct for the same services to work.

This script may come in handy in the following scenarios:

  • Initial configuration, avoid typos
  • Expansion in the infrastructure with load balanced CAS
  • Change in internal FQDN if you change certificate name
  • When you have a total disaster on site 1 and need to fail over to a second site with a passive DAG server that holds all server roles

Please keep in mind:

  • The Script is developed for Exchange 2003 coexistence and migration scenarios
  • The script must not be run in an Exchange 2007 coexistence and migration scenario
  • For InternalURL the script will look for a CASArray (It is recommended to create a CASArray in any scenario)
  • The script assumes there is only one ADsite

About the script:

  • First you will be presented with som choices on what to do
  • InternalURL will autoconfigure based on CASArray
  • ExternalURL will prompt for public FQDN and assume one external address
    • Will use same FQDN for OWA, ActiveSync, Autodiscover and so on
  • Will prompt for Exchange 2003 URL
  • All configuration will output the changes made

 

Update 27.05.2010:

  • Added support for Exchange 2007 and Exchange 2007/2010 coexistence scenarios.
  • The script will check for Exchange version before applying any settings.
  • When applying Exchange 2010 Internal URL the script will match the CAS servers to the correct CASarray in the correct ADsite

 

Update 28.05.2010

  • Added option for checking current configuration
  • Corrected some errors on the Exchange 2007 configuration and listing of URLs
  • Tested in Exchange 2007 only deployments and Exchange 2010 and 2007 coexistence deployments

Web Services InternalURL powershell configuration

If you are using a loadbalancer in front of the ClientAccess server or want to reconfigure the internal URL to point to http and not https you need to reconfigure a couple of services with the correct url so that autodiscover functions properly. To do so I have created a simple script to ease the process using powershell. The script does the following:

  • The server path is specified in the variable
  • Then we use -identity * if you have more than one instance you need to specifiy wich instance you want to configure
  • The url is generated using the variable and the default location of the services files
  • After reconfiguring the services we do a test of the connectivity to verify the configuration
  • Note that custom user credentials is used so that default credentials is not nessesary
  • OWA internal url has to be set manually

To run the script do the following:

  • Copy this into a txt file and rename it to a ps1 file
  • Navigate to the location where the file is saved
  • Use tab to get the correct run syntax

NOTE: This script has been updated in a post related to Exchange 2010 here: https://msunified.net/2010/01/13/configure-exchange-2010-internalurl-powershell-script/

$urlpath = "http://exchange-server.yourdomain.com"

Set-AutodiscoverVirtualDirectory -Identity * –internalurl “$urlpath/autodiscover/autodiscover.xml”
Set-ClientAccessServer –Identity * –AutodiscoverServiceInternalUri “$urlpath/autodiscover/autodiscover.xml”
Set-webservicesvirtualdirectory –Identity * –internalurl “$urlpath/ews/exchange.asmx”
Set-oabvirtualdirectory –Identity * –internalurl “$urlpath/oab”
Set-ActiveSyncVirtualDirectory -Identity * -InternalUrl "$urlpath/Microsoft-Server-ActiveSync"
